Perhaps you should try some spelling variations:
trung khanh » truong khanh, truong thanh, trung phan
trung thanh » truong thanh
thieu xanh » chieu xanh, hieu manh, thien anh
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
cong tan » cong tac, cong san, cong thanh
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 - thanh ((trung khanh) OR (trung thanh)) nhung cong tan tran van~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh ((trung khanh) or (trung thanh)) nhung cong tan tran van*.
