Returning to Nantian refers to the phenomenon that the temperature starts to warm and the humidity rises sharply every spring, which is the name of a weather phenomenon in southern China.

Returning to Nantian is a phenomenon of warmer weather, which generally appears in February and March in spring. The main reason is that after the cold air leaves, the warm and humid airflow quickly counterattacks, resulting in an increase in temperature and air humidity. Some cold objects are easy to produce water droplets when they encounter warm and humid airflow.
