Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tung » thanh cong
hoc thieu » toc thieu, hoc hien
tuan dung » tuan duong, tran dung, tuan dang
tan dung » tran dung, tin dung, van dung
cong tac » cong ty
toan tap » toan ban

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

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