First of all, the place where China looks at the sea starts from the north:

First, Qingdao and Dalian, the most beautiful places in Beihai are still in those two places.

Followed by Zhoushan archipelago, Zhoushan is in the depths of the sea. There are a lot of sea water and beaches on the island, and the scenery is good. Walking around alone is a kind of scenery. The sea water is actually very clean, but for geographical reasons, the color of the sea water is not blue.

Third, Xiamen, Gulangyu Island in Xiamen is very famous, so I won't say much.

Fourth, Hainan, Hainan's seawater is the bluest in China today (not necessarily after Sansha City opened for tourism), with natural white beaches and blue seawater.

Followed by foreign countries, basically islands near China:

Phuket in Thailand, Bali in Indonesia, Rehang Island in Malaysia, Boracay in the Philippines and the famous Maldives.
