Perhaps you should try some spelling variations:
thanh trong » thanh trung, tranh trong, hanh trong
trong thuat » trong hoat, trong thu, trong phat
thuat phan » thuat chan, thuat toan, thuat san
hieu xanh » chieu xanh, hieu nganh, dieu hanh
hieu manh » chieu xanh, hieu nganh, dieu hanh
phan cong » thanh cong
cong tran » cong tan, cong tuan, cong toan
tran van » luan van

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: doc ((hieu xanh) OR (hieu manh)) - thanh trong thuat phan cong tran van ban~.
• Adding a wildcard symbol may retrieve word variants: doc ((hieu xanh) or (hieu manh)) - thanh trong thuat phan cong tran van ban*.
