Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hoc thieu » hoc hien
trung cua » truong cua, trung tuan, trung cap
tranh cua » doanh cua, manh cua
cong dan » cong san, cong tan, huong dan
dan han » dan chan, dan than, dan hanh
han tap » han tai, toan tap, nhan tai

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) OR (toc thieu)) xanh - hanh ((trung cua) OR (tranh cua)) nhung cong dan han tap~.
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (toc thieu)) xanh - hanh ((trung cua) or (tranh cua)) nhung cong dan han tap*.
