Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
trung cap » truong cao, trung tam
cap thanh » cac thanh, lap thanh, tap thanh
cong tap » cuong tap, cong tac, cong tan
quan lap » quan luan, quang lam, quan lang
quan tam » quan tai, quan am, quan nam

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 tinh)) - thanh trung cap thanh cong tap ((quan lap) OR (quan tam))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu tinh)) - thanh trung cap thanh cong tap ((quan lap) or (quan tam))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu tinh)) - thanh trung cap thanh cong tap ((quan lap) or (quan tam))*.
