Is it the same time to enter spring in different parts of China?

In China, the pace of spring moves from south to north.

Nanling Mountain Range, stretching between Guangdong, China, Jiangxi and Hunan, is the place where spring begins in China. This Nanling mountain range, which basically extends from east to west, is like a huge long dike, which often blocks the cold air from the north from going south. Therefore, the coldest time of the year in Lingnan, Guangdong, Guangxi and central and southern Fujian is spring and autumn, while the cold air is resident in Nanling mountain area and Lingbei area, so there is a frosty and snowy winter. The starting point of winter to spring is roughly here.

At the northern foot of Nanling Mountains, spring begins in late February and early March. Then, in spring, we went to the north. On average, Nanchang, Jiangxi entered the spring on March 9, and Changsha, Hunan, in March 10. On March 14, the spring breeze blew the land on both sides of the Yangtze River in Wuhan. In late March, the northward movement accelerated, and Zhengzhou, Henan Province returned to the earth in the spring of March 25th. A few days later, in late March and early April, spring has arrived at the northern end of North China Plain. At this time, Beijing, the capital, and Tianjin, an important industrial city in China, have sent away the cold winter and ushered in a sunny spring.

Walking out of Shanhaiguan, spring slowed down. When spring came to Shenyang, it was April 17, and Harbin on the Songhua River ushered in spring at the end of April. Mohe Village in Heilongjiang Province, the northernmost residential area in China, is the latest place to enter spring in eastern China, and it didn't enter spring until around May 20th.

Counting, it takes about 80 days to start from the northern foot of Nanling Mountain to the northernmost Heilongjiang in spring, with an average of 40 kilometers moving northward every day. But the speed of going north in spring is uneven, sometimes fast and sometimes slow. For example, it only takes 1 week from Xuchang, Henan Province to Baoding, Hebei Province on the North China Plain, with an average of 100 km northward every day. This is because the North China Plain is dry in spring and the temperature rises rapidly, so the pace of spring is accelerated.
