Perhaps you should try some spelling variations:
quan trong » gian trong
hanh tang » hanh trang, hanh mang, hanh tung
chao chu » cho chu, cua chu, cao cho
chu sang » chu bang, thu sang, chieu sang
anh tang » anh bang, anh dang, anh nang
cong ban » cong bang, cong san, cong tan
cong tac » cong ty
hang cau » hang dau, hang ca, nhung cau

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: chao chu sang - ((hanh tang) OR (anh tang)) quan trong ((cong ban) OR (cong tac)) hang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao chu sang - ((hanh tang) OR (anh tang)) quan trong ((cong ban) or (cong tac)) hang cau~".
• Adding a wildcard symbol may retrieve word variants: chao chu sang - ((hanh tang) OR (anh tang)) quan trong ((cong ban) or (cong tac)) hang cau*.
