Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
thanh tran » thanh trang, thanh toan, thanh tra
nhung cong » dung cong, thong cong, nhung don
hoc thieu » toc thieu, hoc hien
hang cong » dang cong, hang nong, bang cong
tran van » luan van
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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 tran van ((nhung cong) OR (hang cong)) dan than cap~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh tran van ((nhung cong) OR (hang cong)) dan than cap*.
