Perhaps you should try some spelling variations:
phuong hanh » phuong thanh, phuong anh, phuong danh
dan phuong » doan phuong, van phuong, lan phuong
hoc thieu » toc thieu, hoc hien
hanh dung » thanh dung, anh dung, hanh dong
hanh toan » thanh toan, khanh toan, manh toan
ho chieu » theo chieu, mot chieu, doi chieu
luan dan » luan danh, luan van, luat dan
toan tap » toan ban

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: ((ho chieu) OR (hoc thieu)) sang - hanh dung luan dan phuong hanh toan tap~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) sang - hanh dung luan dan phuong hanh toan tap*.
