Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
thanh tran » thanh trang, thanh toan, thanh tra
cuong cong » cong cong, luong cong, duong cong
hoc thieu » toc thieu, hoc hien
tran xuan » tran quang, tran van
dung cong » dung trong
dan doan » dan toan, tan doan, van doan

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 manh - thanh tran xuan ((cuong cong) OR (dung cong)) dan doan va~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu manh - thanh tran xuan ((cuong cong) or (dung cong)) dan doan va*.
