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. Choi Wan Estate is one of the few public housing estates in Hong Kong which blocks are not named with character in the estate name (i.e. "Choi" or "Wan"). Instead, the blocks are named based on the Chinese
astronomical matters, for instance, Ngan Ho House (,
lit. galaxy house) and Koon Yat House (, "Koon Yat" meaning "viewing the sun"). The estate is also the namesake for the northwestern
Pacific Ocean tropical cyclone name
Choi-wan. ==Houses==
