Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
hieu manh » chieu xanh, hieu nganh, dieu hanh
hanh hang » thanh hang, hang hang, hanh han
hoc hieu » hoc thieu, hoc hien, doc hieu
dan than » dan chan, ban than, van than
van tuan » van quan, van ban, anh 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 hieu manh - hanh hang va nhung phuong ((dan than) OR (van tuan)) cau~.
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - hanh hang va nhung phuong ((dan than) or (van tuan)) cau*.
