Interpretation of “Looking South of the River” (Part Three): Does the West Lake Longjing Tea Garden Need Human Management?
Let's start with a chart of the Longjing family relationships. The head of the family is Hang Jiahe, who has a daughter named Hang Pan with his former wife Fang Xiling. In the previous article, we mentioned the love at first sight between Hang Pan and Nationalist pilot Cao Jiayuan. Hang Pan is in charge of overseeing hundreds of acres of tea garden, including the famous Lion Peak Hu Gong Temple area. By "overseeing," it mainly means managing the garden rather than preventing others from stealing tea leaves. During the month or so when Longjing tea is picked and processed, there are many people bustling about on the mountain, making it difficult to steal tea. If it's not the picking and processing season, stealing tea would be pointless because the resulting tea would taste terrible and couldn't even be sold as vegetables. Hang Pan's oversight is essentially garden management. The People's Liberation Army took over ten days to capture Hangzhou, officially announcing its liberation on May 3, 1949. The first third of "Looking South of the River" describes the winter and spring before the liberation of Hangzhou. In her diary, Hang Pan wrote: "The fighting has started again, and everywhere… -
The Craft of Making the 24-Ingredient Herbal (Cool) Tea
Cool tea is a beverage commonly prepared in the Chaoshan region by boiling compound or single local herbal ingredients. In the 18th century, Li Qingxiang, a resident of Xikeng Village in Puning, summarized and formulated multiple recipes for cool tea, each composed of twenty-four medicinal ingredients, along with their preparation methods. Through generations of inheritance and innovation, today's 24-ingredient cool tea is made from authentic Chinese medicinal herbs using modern scientific techniques to extract and separate its active components, ultimately producing granulated formulations. The 24-ingredient cool tea is composed of 24 herbs sourced from a list of ingredients that are both food and medicine. The main ingredients include: dandelion, lotus leaf, Houttuynia cordata, mulberry leaf, lophatherum, Prunella vulgaris, gardenia, chrysanthemum, honeysuckle, polygonatum, fat sea date, green plum, kudzu root, Chinese yam, fresh rhizome of reed, hawthorn, lophatherum, lily, jujube, cassia seed, black sesame, poria, tangerine peel, and mint. The 24-ingredient cool tea is guided by traditional Chinese medicine theory and based on herbal ingredients, with effects such as clearing heat and detoxifying, quenching thirst, removing fire and dampness, becoming a popular health care method, especially prevalent in the Chaoshan area. The craft of making the 24-ingredient herbal (cool) tea was… -
Severe Infestation of Tea Looper: How to Cope, Find Out Here
Severe Infestation of Tea Looper How to Cope, Find Out Here It is currently late summer and early autumn, with cool weather in the morning and evening. This year has seen more rain than usual, resulting in vigorous growth of tea plants with lush green leaves, providing rich food for tea plant pests. According to investigations into the infestation of tea loopers in Longwu tea gardens, various age groups of larvae coexist, with severe overlapping generations. In some severely affected areas of tea gardens, the older leaves have been completely consumed, affecting the growth of tea plants, which requires close attention from tea garden managers. Due to differences in cultivation and management practices among individual households, the timing of infestations and the degree of damage vary across different tea gardens, making pest control challenging. It is essential to strengthen pest monitoring through field observations and the use of trapping devices, promptly understanding the dynamics of pest outbreaks and implementing appropriate measures: 1. Turn on insect-killing lamps, taking advantage of the fact that adult tea loopers are most active between 8:00 PM and 10:00 PM. Set the operating times of the lamps accordingly, ideally using a light-controlled mode where they automatically… -
Naxian Village, New Comfort Town: United Development for a Thriving Tea Industry
In the pleasant April weather, with a gentle breeze blowing. In the tea garden of the Pomegranate Seed Group in Naxian Village, New Comfort Town, Mengjiang County, old tea trees taller than a person are sprouting new green leaves. Tea farmers are seen climbing wooden scaffolds or pulling on tree branches to pick the fresh buds. Stepping into the home of Li Kang, a tea farmer in the Pomegranate Seed Group of Naxian Village, New Comfort Town, one is greeted by the aroma of tea. He is diligently inspecting every step of the tea processing and production. Before long, freshly stir-fried spring tea is ready. According to Li Kang, Naxian Village has tea trees over a hundred years old. However, due to a lack of business management concepts, the villagers operated independently without forming a united front, which prevented them from capitalizing on their valuable resource. In 2022, Li Kang registered Mengjiang New Comfort Youzhi Tea Processing Factory, leasing more than 50 mu (approx. 33,333 square meters) of land with over 1,600 tea trees aged 80 years or older across two groups, Baiye Village and Pomegranate Seed Group. He invited experts with over 30 years of experience in producing Pu'er… -
The Four Brothers of Purple Clay Pots: Lotus Seed, Drum Imitation, Duetsphere, and Duet, can you still tell them apart?
The four types of pots—Lotus Seed, Drum Imitation, Duetsphere, and Duet—are very similar and often confused. Let's clarify these four pot styles: 【Lotus Seed】 【Drum Imitation】 【Duetsphere】 As shown above, the Drum Imitation is generally the shortest among these four pots, with a handle that may have an inverted ear (a small ear-like protrusion at the end). The Lotus Seed pot is slightly taller than the Drum Imitation and also has an inverted ear on its handle. The Duetsphere pot is the tallest of the four, and its handle does not have an ear-like protrusion. The bottoms of the first three pots—Drum Imitation, Lotus Seed, and Duetsphere—are all fitted with a false bottom; looking straight down, there is no visible "foot," as the body curves directly to the bottom. The last style, the Duet pot, easily reveals its bottom, which features a "line" or "foot." This makes it relatively easy to distinguish. Its handle also lacks an ear-like protrusion. Lotus Seed The "Lotus Seed" pot shape consists of circles stacked from small to large, symbolizing the Chinese traditional meaning of "successive generations of noble offspring." Ancestral customs often use homophones for auspiciousness. The basic characteristics of the Lotus Seed pot…- 3

What is Wuyi Caicha?
When did the variety of Wuyi Rock Tea originate? According to "The New Gazetteer of Tong'an County," "Wuyi tea was originally wild, not planted by human hands. It is said that it was first discovered by an old man... The old man first offered the tea and after his death, he was revered as a mountain deity and enjoyed temple sacrifices." In Fan Zhongyan's "Song of Tea Competition with Zhang Min," it states: "The miraculous tea by the stream surpasses all in the world, cultivated since ancient times by the immortals of Wuyi." The "immortals of Wuyi" likely refer to the distant ancestors of the Wuyi tea region, traditionally believed to be Wuyi Jun or Pengzu. According to Hu Haochuan's research, Wuyi Caicha evolved from a wild species. Professor Zhuang Wanfang believes that Wuyi tea was cultivated by ancients or possibly introduced from Wulong Ridge in Zhejiang Province. Caicha is the mother of Wuyi teas and is the collective term for the sexually propagated group of tea trees in Wuyi. This means these teas are as common as the vegetables grown around the house, only for everyday drinking. In the natural environment of Wuyi Mountain, due to the cross-pollination of… -
“Grass to Suppress Grass” Method: Intercropping White Clover in Tea Gardens
Tea gardens are characterized by a diverse range of weeds, complex weed communities, and strong stability. According to incomplete surveys and statistics, there are as many as 202 common weed species found in domestic tea gardens, belonging to 49 families and 163 genera. Weeds can impact the growth of tea plants, causing symptoms such as stunted growth, yellowing leaves, leaf drop, and delayed development. They may also carry diseases or pests that affect tea plants directly or act as intermediate hosts, indirectly impacting the growth and development of tea plants. "Grass to suppress grass" is an integral part of the green and efficient prevention and control technology system for Guizhou tea gardens, embodying the concept of "ecology at its root, agriculture at its core, and biological control first." Planting white clover in tea gardens can effectively suppress weeds and resist tea plant diseases and pests. Below are key technical points for reference. White clover in tea gardens and pollinating insects - bees Intercropping white clover in tea gardens Effective "grass to suppress grass" In recent years, research teams from Guizhou University, the Provincial Plant Protection and Inspection Station, the Provincial Academy of Agricultural Sciences, and the Provincial Soil and Fertilizer… -
Why does Wuyishan produce fine tea? The “Three Teas” initiative spreads its fragrance far and wide!
When the journalist arrived in Xingcun Town, Wuyishan City, on the 13th, the town's mayor, Wu Wang, warmly greeted us and invited us to taste some tea. Boiling water was poured into a cup, and as the leaves unfurled in the water, the tea broth gradually turned amber, emitting a rich aroma. "This is the main venue for professional tea competitions that have been held here for 800 years. As they say, 'Tea doesn't truly emit its fragrance until it reaches Xingcun.' We are a significant hub along the ancient Tea Road and the birthplace of black tea in the world." Mayor Wu said with a smile. Photo by Shi Chenjing, Fujian Daily – Swallows' Nest Ecological Tea Garden A short distance away lies the Swallows' Nest Ecological Tea Garden. Although the tea-picking season had passed, there were still five or six tea farmers moving about deep within the garden, pruning the tea plants to lay the groundwork for an increased yield in the coming year. Tea farmer Yang Wen Chun bent down and pointed to the soybeans planted among the tea plants: "Professor Liao Hong from Fujian Agriculture and Forestry University proposed an intercropping model of planting soybeans in…- 6

Deep, Intermediate, and Shallow Cultivation in Tea Gardens
There’s a folk saying: “When the hoe digs deep, there’s no lack of gold or silver.” Winter management of tea gardens is crucial for laying the groundwork for a bountiful harvest the following year, ensuring high-quality tea based on the “heaven, earth, human, and seed” foundation. The tea garden should be pruned into a cockscomb shape or uniformly flat, with the choice of heavy pruning or light trimming of side branches depending on the growth status of the garden. The appropriate height of shrub-like tea plants benefits both their growth and the ease of picking fresh leaves. After pruning, the old leaves can be buried through deep cultivation to ferment into organic fertilizer, which loosens the soil and promotes the growth of tea plants. Weeds along the edges or nearby can also be used to cover the garden, providing insulation, water retention, nutrient conservation, and support for microorganisms. Once these weeds decompose, they too become organic fertilizers for the tea garden. Many tea gardens in my hometown are terraced in ridges. For those with low embankments, adding a layer of turf and garden soil can help reduce soil erosion and nutrient loss, maintaining the vigorous vitality of the tea plants.… -
Wuxi, Chongqing: Ancient Eagle Tea Trees in Bloom
Leopard-skin-like tree trunks, arm-thick branches, and scattered blossoms among the tea leaves... Recently, on several ancient eagle tea trees in Wuxi, Chongqing, tea flowers have bloomed, clear and delicate.It is said that the eagle tea comes from the evergreen tree Alseodaphne semicarpifolia of the Lauraceae family, with very hard seed shells. According to legend, the seeds need to be swallowed by eagles, and after the shell is softened by stomach acid and excreted, they can germinate, hence the name "eagle tea." In Wuxi, there are more than 50,000 mu (about 3,333 hectares) of eagle tea planted, including ten eagle tea trees that are a thousand years old and 2,500 eagle tea trees over a hundred years old.
