牛池灣
Choi Wan Estate was the site of Ngau Chi Wan Village. Its name Choi Wan fits its geographical position because "Wan" (i.e. Choi Wan Estate, "Wan" means cloud in Cantonese) is above "Hung" (i.e. Choi Hung Estate, "Hung" means rainbow in Cantonese). The estate started construction in 1976 and finished in 1979.
