Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
dung cong » dung trong
thanh cap » thanh lap, hanh cap, thanh ca
trung va » truong va, trang va, trung ha
cong van » cong vang, cong san, song van
than cap » khan cap, thanh lap, thanh cac
va dung » van dung, va duong, vat dung

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - thanh trung va dung cong van ((thanh cap) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - thanh trung va dung cong van ((thanh cap) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - thanh trung va dung cong van ((thanh cap) OR (than cap))*.
