Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, thien anh, thien danh
hieu manh » chieu xanh, hieu nganh, dieu hanh
trung hoa » trung hoc
bang cong » dang cong, bang song, hang cong
trung ha » trung hoc, trung tam, trung cap
than cap » khan cap, thanh lap, thanh cac
cong he » cong che, cong ha, cong de
he than » he thong, le thanh, de thanh

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 (hieu manh)) - hanh ((trung hoa) OR (trung ha)) bang cong he than cap~.
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (hieu manh)) - hanh ((trung hoa) or (trung ha)) bang cong he than cap*.
