How about Guangzhou and Chengdu, which represent South China and Southwest China respectively?
Guangzhou, one of the southernmost cities in China, is called Lingnan. This city is also called Yangcheng and Wuyang. It is one of the earliest cities of reform and opening up, so compared with Chengdu, Guangzhou has an earlier opening degree and more migrant workers.
Guangzhou is located in the hinterland of the Pearl River Delta, together with the international metropolis Hong Kong and the frontier city of reform and opening up Shenzhen, forming the brightest pearl of the Pearl River Delta.
Guangzhou is warm in winter and hot in summer, so I live in Guangzhou in winter and hardly need to wear winter clothes. But summer in Guangzhou is longer and hotter.
Chengdu is located in the west of China, Sichuan Basin, the hinterland of Chengdu Plain, and the land of abundance. There are Qinling Mountains in the north, western Sichuan Plateau in the west and Daba Mountain in the south, which makes Chengdu warm in winter and cool in summer, with no heat in summer and no severe cold in winter.
Chengdu has been rated as the happiest city in China for several years. Its labels are food, beautiful scenery and beautiful women.
The giant panda is a rare and endangered wild animal in the world and a national treasure of China. Its habitat is in Chengdu, Sichuan.
Summer in Chengdu and winter in Guangzhou are good choices!
