Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
xuan cuong » xuan huong, xuan truong, quang cuong
cuong cong » cong cong, luong cong, duong cong
hieu manh » chieu xanh, hieu nganh, hien hanh
tran xuan » tran quang, tran van
dan thanh » dang thanh, danh thanh, ban thanh
thanh lap » thanh san, phan lap, thanh hai
cong dan » cong san, cong tan, huong dan

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 ((hieu manh) OR (dieu hanh)) - thanh tran xuan cuong cong dan thanh lap~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (dieu hanh)) - thanh tran xuan cuong cong dan thanh lap*.
