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
nhung cong » dung cong, thong cong, hang cong
trung va » truong va, trang va, trung ha
cong ban » cong bang, cong san, cong tan
than cap » thanh lap, thanh cac, than cua
khan cap » khan ap, khoan cam, phan cac

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