Climatic characteristics of Bailu solar term what does Bailu solar term eat

Bailu solar term is one of the 24 solar terms in China. After entering Bailu, the weather gradually turns cool. So what are the climatic characteristics of Bailu solar term? What is the traditional custom of Bailu solar term? Let's get to know each other.

The origin of Bailu

Bailu is one of the 24 solar terms in the lunar calendar. When the sun reaches 165 degrees of the Yellow longitude, Bailu solar terms are handed in. Bailu is the third solar term of autumn, indicating the end of the season of mengqiu and the beginning of the season of mid autumn. Dew is a drop of water formed by the condensation of water vapor on the ground or near earth objects due to the decrease of temperature. Therefore, Bailu is actually a sign that the weather has turned cold. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. The temperature difference between day and night can reach more than ten degrees. Yang Qi reaches its peak at the summer solstice, when the extremes of things turn against, Yin Qi also rises at this time.

Climate characteristics of Bailu

After the dew season, the summer monsoon is gradually replaced by the winter monsoon. The cold air changes to attack, and the warm air gradually retreats. When cold air moves southward in batches, it often brings a certain range of cooling range. People like to use the proverb "White Dew, autumn wind night, cool night" to describe the situation that the temperature drops faster.

At this time, the precipitation in the north of China is obviously reduced, and the autumn is crisp and dry. During this period, the first autumn rain in the middle and lower reaches of the Yangtze River can often alleviate the water shortage in the early stage. However, if the cold air meets the typhoon, or the cold and warm air are equally matched, when the two sides are struggling with each other, the rainstorm or low-temperature continuous overcast rain will be harmful to the autumn crop growth.

In the east of Southwest China, South China and West China, continuous rainy weather often occurs. There may also be heavy rain caused by tropical weather system (typhoon) in southeast coast, especially in South China coast. In addition, at this time, some areas may be dry in autumn, forest fire, early frost and other weather.

Traditional customs of Bailu

Sacrifice to the king Yu

Bailu season is also the day when people of Taihu Lake sacrifice Yu king. Yu Wang is the legendary hero of water control, Dayu. Fishermen near Taihu Lake call him "water Bodhisattva". On the eighth day of the first month, the Qingming Festival, the seventh day of the seventh day of the seventh month and the Bailu festival every year, there will be an incense festival for Yu king. Among them, Qingming Festival and Bailu spring and Autumn Festival are the largest, lasting for a week.

During the sacrificial activities, "fishing and killing" is a play that must be performed. It places people's hope and yearning for a better life.

According to Chen Chen's later generations of the marsh, fighting against the fisherman, also known as "qingdingzhu" and "fishing tax", has been performing on the stage for a long time.

Eat longan

There is a tradition in Fuzhou called "Bailu must eat longan". The folk meaning is that eating longan on Bailu's day has great body tonic effect. Eating a longan on this day is equivalent to eating a chicken. It sounds too exaggerated, but there are still some reasons. Because longan itself has many functions, such as tonifying qi and spleen, nourishing blood and calming nerves, moistening and beautifying skin, etc., it can also treat anemia, insomnia, neurasthenia and many other diseases, and before Bailu Longan is big, with small kernel and sweet taste, so it's better for Bailu to eat longan. Whether it's a real tonic or not, it's a tonic. So people in Fuzhou are used to this traditional custom.

Wenzhou and other places in Zhejiang Province have the custom of Bailu Festival. People in Cangnan, Pingyang and other places collected ten kinds of white on this day (also known as "three kinds of white") to snuggle up black bone and white feather chicken (or duck). It is said that after eating, it can nourish the body and remove the wind (arthritis). This "ten kinds of white" is ten kinds of herbs with the word "white", such as white wood model, white hair bitter and so on, to correspond with "White Dew" literally.

White Dew tea

When it comes to Bailu, the tea loving old Nanjing is very fond of Bailu tea. At this time, the tea tree after the summer heat, before and after Bailu is an excellent period for its growth. Bailu tea is neither as fresh and tender as spring tea, nor as dry and bitter as summer tea.

At this time, the spring tea stored at home has been basically 'consumed', and Bailu tea is being connected, so before and after Bailu, some tea customers will send someone to buy Bailu tea.

Bailu rice wine

There has always been a brewing custom in Xingning, Sandu and liaojiang areas of Zixing. Every year, when the White Dew Festival comes, every family will make wine and treat guests and receive people with local wine. Its wine is warm, slightly sweet, called "white rice wine".

The best product of Bailu rice wine is chengjiu, which is named after Chengjiang river water. Chengjiu is a tribute wine in ancient times and has a long reputation. It is recorded in shuijingzhu that 'there is Lushui in CHENXIAN County, which goes out of the northwest of Hougong mountain in the east of CHENXIAN county and flows to the south. It is called chengshuixi. The county has a tavern that will brew on the famous day of the mountain, Cheng liquor, and the same is offered. '

Jiuyuzhi) said: 'Chengshui is in Xingning County, Chenzhou today. It comes from Chengxiang. This water makes wine. It's named "chengjiu". It's different from wine. '

Chengxiang is now the Sandu and liaojiang corpse belt. Zixing was called Xingning from the Southern Song Dynasty to the early years of the Republic of China.

The brewing method of Bailu rice wine is quite unique, besides taking water and selecting solar terms. First brew white wine (commonly known as "local burning") and glutinous rice wine, then pour the white wine into the wine according to the proportion of 1:3, and put it into the jar for drinking. If the process wine is made, it must be mixed with a proper amount of mixed water (boiled with mixed water), then sealed in the jar, buried in the ground or cellar, or buried in the mud of the fresh cattle pen, and it can only be taken out for drinking for several years or even ten years.

Cheng wine, which has been buried for decades, is brown and red. It is easy to be imported, fragrant and has a strong aftereffect.

"Xingning county annals" compiled in the first year of Guangxu's reign in the Qing Dynasty (1875) said: 'the longer it is, the more fragrant it will be.' it can be brewed for thousands of days and drunk at home. '

It is also recorded in shuijingzhu that Ren family, a writer of Liang Dynasty in the Southern Dynasty, had a chat with Liu Yao, a friend of his. "Ren called Liu Yao and said, & lsquo; if there is a thousand li of wine, it should be an empty word? & rsquo; Yao said, & lsquo; there is a thousand li of wine in Chengxiang of Guiyang, which is also an example of waking up after drinking at home. In the southern Liang Dynasty, Xingning belonged to Guiyang County. There is also a custom of brewing Bailu rice wine in the old Nanking of Southern Jiangsu and Zhejiang. In the old days, Bailu rice wine was made every year in the rural areas of Jiangsu and Zhejiang to entertain guests. People often brought Bailu rice wine to the city. Bailu rice wine is brewed from glutinous rice, sorghum and other grains, which is slightly sweet, so it is called Bailu rice wine.

Until the 1930s and 1940s, there were still dozens of Bailu rice wine in the hotels in Nanjing, which gradually disappeared.
