Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien danh
nhung cong » dung cong, thong cong, hang cong
thien anh » thien danh, tien anh, thien thanh
hoa phan » hoa dan, co phan
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cap » khan cap, thanh lap, thanh cac
hoa van » hoa dan, hoang van, hoa lang

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