Perhaps you should try some spelling variations:
thanh thuong » thanh huong, thanh chuong, thanh phuong
chieu sang » chieu sach, chieu xanh, hieu lang
ho chieu » theo chieu, hoc thieu, doi chieu
dan dung » van dung, tin dung, ap dung
cong ban » cong bang, cong san, cong tan
than cap » thanh lap, thanh cac, than cua
khan cap » khan ap, khoan cam, phan cac
cao ung » cao dung, cac ung, cho ung

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 sang - thanh thuong ((dan dung) OR (cao ung)) cong ban ((than cap) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh thuong ((dan dung) or (cao ung)) cong ban ((than cap) OR (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh thuong ((dan dung) or (cao ung)) cong ban ((than cap) OR (khan cap))*.
