Perhaps you should try some spelling variations:
thieu manh » hieu manh, tien manh, trieu minh
quang hang » quang hoang, quang khang, quang thang
hoc thieu » toc thieu, hoc hien
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
hang cong » dang cong, hang nong, bang cong
manh toan » thanh toan, anh tuan, tinh toan
van than » van thanh, van thang, van tuan

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 - hanh tinh quang hang cong ((manh toan) OR (van than)) ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu manh - hanh tinh quang hang cong ((manh toan) or (van than)) ban*.
