Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh tung, thanh hung
hoc thieu » toc thieu, hoc hien
hung cong » nhung cong, hung cuong, phung cong
doc hieu » toc thieu, hoc hien
dung tam » duong tam, dung tai, dung lam
tam hung » tam huong, cam hung, tai hung
cong san » cong tac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((doc hieu) OR (hoc thieu)) xanh - thanh dung tam hung cong san ((toan ban) or (van ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (hoc thieu)) xanh - thanh dung tam hung cong san ((toan ban) OR (van ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) OR (hoc thieu)) xanh - thanh dung tam hung cong san ((toan ban) or (van ban))*".
