Perhaps you should try some spelling variations:
hanh trinh » canh tranh
chua xang » chua nang, chuc nang, chu bang
cho chua » cho chu, cho cua, ho chua
cua hang » cua dang, cua nhung, cua ban
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than tap » toan tap, han tap, phan tap

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: cho chua xang - ((hanh trinh) OR (hanh chinh)) ((cua hang) OR (cua cong)) cong dan than tap~.
• Adding a wildcard symbol may retrieve word variants: cho chua xang - ((hanh trinh) or (hanh chinh)) ((cua hang) or (cua cong)) cong dan than tap*.
