Perhaps you should try some spelling variations:
trong tranh » trong thanh, trong trang, trong nganh
trung tranh » trung thanh, trung tran, truong thanh
chieu sach » chinh sach, chiet tach, chieu sang
nhieu tang » chieu sang, hieu lang, nhiet nang
trong san » trong cac, cong san, dong san
san toan » van toan, dan toan, manh toan
toan tap » toan ban

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 sach) OR (nhieu tang)) - hanh ((trung tranh) OR (trong tranh)) dung trong san toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (nhieu tang)) - hanh ((trung tranh) OR (trong tranh)) dung trong san toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (nhieu tang)) - hanh ((trung tranh) OR (trong tranh)) dung trong san toan tap*.
