Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hanh trung » thanh trung, hanh trang, danh trung
manh trung » manh tung, thanh trung, manh hung
hoc thieu » toc thieu, hoc hien
phan cong » thanh cong
cua phan » cua nhan, cua phap, cua han
cong tan » cong tac, cong san, cong thanh
tran ban » tranh ban, toan ban, tran bai
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: hoc thieu xanh - ((hanh trung) OR (manh trung)) cua phan cong tan ((tran ban) OR (tran van))~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh trung) or (manh trung)) cua phan cong tan ((tran ban) or (tran van))*.
