Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
doanh thanh » danh thanh, doanh nhan, dinh thanh
truong cong » trong cong, truong dong, truong long
thieu lang » hieu lang, thieu khang, thieu quang
ca truong » cac truong, cua truong, cao truong
cong dan » cong san, cong tan, huong dan
dan van » dang van, doan van, dao 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: toc thieu lang - ((chinh doanh) OR (doanh thanh)) ca truong cong dan van ban~.
• Adding a wildcard symbol may retrieve word variants: toc thieu lang - ((chinh doanh) or (doanh thanh)) ca truong cong dan van ban*.
