Perhaps you should try some spelling variations:
thanh trung » thanh tung
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
cua dang » cua cong, cua ban
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban
ca dan » cac dan, ca dao

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: hoc thieu xanh - thanh trung ((cua dang) OR (ca dan)) cong tan ((toan cau) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh trung ((cua dang) or (ca dan)) cong tan ((toan cau) or (toan tap))*.
