Xichi is a result of the Angkor Kingdom Water Conservancy Project. See the introduction, in the 1st century AD, Angkor vigorously built water conservancy, and built the East Pool, Xichi, Beichi, Luolaichi, Royal Bath and Angkor Temple moats, Tongwangcheng moats. The grand water system that communicates thousands of small pools and pipes. This huge water system, in addition to irrigation for farmland, also takes into account the water and drainage of cities and temples, is the contribution of the Kingdom of Angkor to human civilization. But now the water project has been ruined, leaving Xichi to prove the existence of the water project. Now Xichi is more a attraction for local residents to relax here, like the beach in Siem Reap.
