Perhaps you should try some spelling variations:
hieu manh » chieu xanh, hieu nganh, dieu hanh
manh tung » manh hung, thanh tung
lang cong » dang cong, bang cong, hang cong
sang than » cang thang, dang thanh, sang tao
hoc hieu » hoc thieu, hoc hien, doc hieu
anh dung » anh dong, anh huong, sach dung
san than » san thanh, ban than, van than
va lang » va nang, 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 hieu manh - ((manh tung) OR (anh dung)) va lang cong ((san than) OR (sang than)) cau~.
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - ((manh tung) or (anh dung)) va lang cong ((san than) or (sang than)) cau*.
