Perhaps you should try some spelling variations:
khong cong » thong cong, khong cang, chong cong
hoc thieu » toc thieu, hoc hien
trung cua » truong cua, trung tuan, trung cap
tan thanh » tran thanh, tang thanh, toan thanh
thanh cha » thanh ha, thanh nha, thanh phan
ho chieu » theo chieu, doi chieu, mot chieu
tung cua » tuong cua, dung cua, tang cua
cong tan » cong tac, cong san, cong thanh

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)) xanh - manh ((tung cua) OR (trung cua)) khong cong tan thanh cha~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - manh ((tung cua) or (trung cua)) khong cong tan thanh cha*.
