Taklimakan Desert is located in the basin, surrounded by rivers flowing into the basin, disappearing into the long yellow sand and gathering under the desert, forming a vast underground ocean.
According to the test data, the total amount of water resources under the Taklimakan desert exceeds 8 trillion tons, and the groundwater level in most areas is lower than 10m. If sand and groundwater are exchanged and water runs on the sand, it will be a fresh water ocean with a depth of 24 m and a square garden with an area of 327,000 km2, which is enough to turn three Jiangsu provinces or 19 Beijing into aquariums.
