Will it always be cloudy on cloudy days in Sailimu Lake?

No. Climate and weather are not static. Changes in natural factors will affect the energy budget on the earth's surface, thus changing the earth's climate. Sailimu Lake area is surrounded by mountains and glaciers, forming a closed alpine basin water system. The average annual precipitation on the lake is about 450mm, mostly in April-August. It can be seen that all months except April-August are sunny. Therefore, Lake Sailimu will not be cloudy all the time.
