Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
tan thanh » tran thanh, tang thanh, toan thanh
thanh cap » thanh lap, hanh cap, than cap
toan van » toan ban, tan van, toan va
tran van » luan van
cong tan » cong tac, cong san, cong thanh

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh ((toan van) OR (tran van)) nhung cong tan thanh cap~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh ((toan van) OR (tran van)) nhung cong tan thanh cap*.
