Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang
chieu tinh » trieu tinh, lieu tinh, chau tinh
hieu manh » hieu nganh, dieu hanh, hien hanh
dung cong » dung trong
trung va » truong va, trang va, trung ha
cong tac » cong ty
tac tran » tan tran, tac trai, tac tren
tran cao » toan cao, tran chau, trang cho
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 (hieu manh))) OR (chieu tinh)) - thanh trung va dung cong tac tran cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (hieu manh))) or (chieu tinh)) - thanh trung va dung cong tac tran cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) OR (hieu manh))) or (chieu tinh)) - thanh trung va dung cong tac tran cao*.
