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 ha » trung hoc, trung tam, trung cap
ha thong » hoa thong, nha thong, he thong
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cao » toan ban, toan tap

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 ha thong ((cong dan) OR (cong tan)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu tinh)) - thanh trung ha thong ((cong dan) or (cong tan)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu tinh)) - thanh trung ha thong ((cong dan) or (cong tan)) toan cao*.
