Introduction: Beginning of Summer is one of the important solar terms. Many people will choose farming activities based on the solar terms. So what is the origin of Beginning of Summer? It’s March again, the season of colorful flowers and green willows. All things come back to life, presenting a beautiful scene of vitality. The Fortune Teller website will analyze every detail of the third month of the lunar calendar in 2018 for you! Lixia is the 7th solar term in the 24 solar terms of the lunar calendar and the first solar term of summer, marking the official beginning of the Mengxia season. The Lixia solar term begins when the sun reaches 45 degrees of the ecliptic longitude. When the Dipper points to the southeast, it is the beginning of summer. All things grow at this time, hence the name the beginning of summer.
"Collection of Explanations of the 72 Lunar Calendars" states: "The beginning of summer is the festival of April. The meaning of the word 'beginning' is the same as that of 'spring'. Summer means 'fake'. At this time, everything is fake and great."
Every year on May 5th or 6th, the sun reaches 45° of the ecliptic longitude, which is the "Lixia" solar term. This solar term was established in the late Warring States Period (239 BC), heralding the change of seasons. It was the day when summer, which was one of the four seasons divided by the ancient lunar calendar, began. For example, the Yi Zhou Shu Shi Xun Jie says: "On the day of the beginning of summer, crickets chirp. Five days later, earthworms come out. Five days later, cucumbers grow."
That is to say, during this solar term, the first sound you can hear is the chirping of clams (i.e. katydids) in the fields (some say it is the croaking of frogs), then you can see earthworms digging in the soil, and then the vines of pumpkins begin to climb and grow rapidly, which describes the phenological scene at the beginning of summer. It is said in the Collection of Explanations of the 72 Seasonal Changes in the Lunar Calendar: "Li means establishment and beginning, and Xia means vacation. At this time, all things are vacationing and growing." The word "vacation" here means "big", which means that the plants sown in spring have grown upright. According to records, during the Zhou Dynasty, on the day of the Beginning of Summer, the emperor would lead civil and military officials to the southern suburbs of the capital to welcome summer and hold a ceremony to welcome summer. The emperor and his ministers all wore vermilion ceremonial robes and vermilion jade pendants. Even the horses and chariot flags had to be vermilion to express their desire for a good harvest and good wishes. They also ordered officials such as the Minister of Works to go to various places to encourage farmers to work hard.
Climate characteristics According to climatological standards, summer begins when the daily average temperature stably rises to above 22℃. Around the "Beginning of Summer", only the areas south of the line from Fuzhou to Nanling in China truly enter summer, while parts of the Northeast and Northwest have just entered spring. The average temperature in most parts of the country is around 18-20℃.
The temperature in the rest of South China is around 20℃; while the low-altitude river valleys feel the summer heat as early as mid-April, and the temperature reaches above 24℃ at the beginning of summer.
After the beginning of summer, the south of the Yangtze River officially enters the rainy season, with a significant increase in rainfall and rainy days. The continuous rain not only causes damage to crops. It can also cause the spread of various diseases.
