Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
hanh trung » thanh trung, hanh trang, manh trung
trung dap » trung cap, trung dai, trung dam
dap luong » dai luong, da luong, do luong
cong ban » cong bang, cong san, cong dan
cong tan » cong tac, cong san, cong thanh
than cap » khan cap, thanh lap, thanh 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 sang)) - hanh trung dap luong ((cong ban) OR (cong tan)) than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - hanh trung dap luong ((cong ban) OR (cong tan)) than cap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - hanh trung dap luong ((cong ban) OR (cong tan)) than cap*.
