How long does Nanchang go back to Nantian?

Nanchang's return to Nantian usually lasts 3-5 days. Usually supplemented by cold air, it disappears immediately. If it keeps warm, it lasts for 3-5 days, and if it lasts for a long time, it can last for more than half a month.

Returning to Nantian often occurs in the season of alternating February and March, and generally ends in April. If we want to get rid of this weather completely, it must be after Qingming every year, because it will rain in Mao Mao every Qingming, and spring ploughing after the holiday is like this. Generally, you can get rid of such continuous weather after mid-April.
