Lìxià (literally "start of summer" or "inauguration of summer") is the 7th solar term according to the traditional Chinese lunisolar calendar, which divides a year into 24 solar terms .[1]
It begins when the Sun reaches the celestial longitude of 45° and ends when it reaches the longitude of 60°. The word Lixia most often refers specifically to the first day of this period, the day when the Sun is exactly at the celestial longitude of 45°. In the Gregorian calendar, this is around May 5, and the Lixia period ends with the beginning of the next solar term, Xiaoman, around May 21.[2] [3]
Lixia signifies the beginning of summer in Chinese culture,[4] and due to the importance of summer in the agrarian society of ancient China, the day is associated with many cultural traditions, which vary by region.
Each solar term can be divided into three pentads . They are the first pentad (初候), second pentad (次候), and last pentad (末候). Lixia's pentads are:[5] [6]
According to the ancient Book of Rites, on Lixia the emperor would lead the Three Ducal Ministers, the Nine Ministers, and senior officials in greeting the summer, and the day was celebrated with gifts and music. From James Legge's translation:[7]
A number of Lixia traditions relate to food. Some traditions symbolize neighborliness, including a traditional Lixia food, "seven-family porridge" .[8] Traditionally, people would ask for rice from their neighbors, cook it into rice porridge with multicolored beans and brown sugar, and share it with family, friends, and neighbors.[8] A similar tradition, with the same significance, is "seven-family tea" : people would ask each of their neighbors for a few tea leaves and mix them together to brew tea.[8]
For farmers in parts of China, Lixia is traditionally the time of the "three new" crops: cherries, green plums, and millet.[8] These three early-ripening crops are typically ready to be eaten around Lixia, and traditionally some people would use them as religious offerings.[8] In other parts of China, other crops become available around Lixia.[8] Near Zhejiang's Guxi River, people eat Lixia cakes (made from rice or wheat), Chinese scholartree seeds, tofu, and bamboo shoots.[4] A poem from Hangzhou mentions plums, flatcakes, cherries, cured meat, fish, black rice cakes, three-colored amaranth, sea snails, salted duck eggs, roast goose, broad beans, and rice wine fermentation, all of which were associated with Lixia.[8] In contrast, in Taiwan, the arrival of crops is a less relevant part of Lixia, as the warm climate means that a variety of crops are available year-round.[8]
In Tangxi, Hangzhou, in addition to pastries and salted duck eggs, Lixia foods include colorful "Lixia dogs" made from glutinous rice.[9] [10]
Another tradition is weighing people, a complicated process that dates back to ancient China, before the existence of modern scales.[4] [8] Each person is weighed by sitting on a plank suspended from roof beams with hemp rope,[8] or alternatively, an iron weight is hung from one side of the plank while the person sits in a bamboo basket hanging from the other side.[11] This tradition is especially popular with children.[8] [11] With modern technology it has largely disappeared,[8] but it is preserved in some communities as a symbol of good health for the coming summer.[11]
According to folk sayings, Lixia is a busy time for farmers.[12] South of the Yangtze River, it marks the beginning of the rainy season.[13] In some areas, it signifies the end of the spring tea-picking season.[14]
Historically, people used the sounds of animals on Lixia to predict the year's weather.[8] According to a belief mentioned in the Book of Zhou, if crickets (and according to some interpretations, frogs) do not make noise on Lixia, the year will be very rainy with a risk of flooding.[8]
