For example, large airports can be built and small warehouses and houses can be built. The islands face each other and it is easy to take care of each other. The shallow lake in the middle is rich in aquatic resources, and there are not many reefs in the shallow lake, mostly on the east side, with good navigation channels and fishing grounds. There are many "doors" in the shallow lake that are connected with the open sea, which is a good place for ships to berth for shelter from the wind. There is fresh water supply on the island, such as Ganquan Island, which is famous for its Ganquan. There is also an oil prospect nearby, so the Yongle Islands have a bright future.
Geographically, Yongle Atoll is just to the east of Nanyang Strait, with a good traffic position. Historically, foreign invasions mostly came from the southwest, and from the perspective of defense, Yongle Atoll is also very important.
