Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tung » thanh cong
cong cong » cong dong, trong cong, dung cong
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than ban » thanh ban, toan ban, than man

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: doi ((chieu xanh) OR (chieu tinh)) - ((thanh trung) OR (thanh tung)) cua cong cong tan than ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu tinh)) - ((thanh trung) OR (thanh tung)) cua cong cong tan than ban~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu tinh)) - ((thanh trung) OR (thanh tung)) cua cong cong tan than ban*.
