Four or nine days * * * How many days?

April 9th is the 29th to 36th day from winter to the future, which is * * * nine days.

It has been a cold day in China since the winter of November. Astronomical experts say that the Ninth Five-Year Plan is a more applicable solar term in northern China, especially in the middle and lower reaches of the Yellow River.

It started from the day when it met Ren in winter and entered the "number nine", commonly known as "cross nine". From then on, it was called "Nine" every nine days. After nine "nines", it's just 8 1 day, and then spring blossoms.

In ancient times, especially in northern China, the conditions for working people to keep warm from the cold were simpler than their descendants. Winter is regarded as a threat and punishment, which directly affects people's mood and even makes them feel that winter is inexplicably long. At that time, in order to survive the long winter, the people of China invented the method of "counting nine" to pass the time, so as to alleviate the psychological crisis under the threat of winter. At that time, it was a carefree state to count nine around your family.
