Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
phuong dan » phuong danh, phuong doan, huong dan
hieu manh » chieu xanh, hieu nganh, dieu hanh
tang luan » dung luan
hoc hieu » hoc thieu, hoc hien, doc hieu
dan chan » dan gian, dan ca, van chat
ban cua » ban quan
chan tu » phan tu, han tu, chon tu

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 ((tang luan) OR (ban cua)) nhung phuong dan chan tu~.
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - hanh ((tang luan) or (ban cua)) nhung phuong dan chan tu*.
