Because of their small area, low terrain and lack of fresh water, these islands are mostly desert beaches with few plants, such as Sanshizi, Beisha, Zhongsha and Xixinsha because of their small area, which are often attacked and eroded by storm surges. If Xisha is less than Qilianyu, it will not really appreciate the charm of coral reefs. There are abundant tropical vegetation and unique natural scenery on the islands of Qilian Island. There are also a large number of seabirds living on the islands. There are many seabird eggs on the coral sands of the seashore, which can be found at any time.
