Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh phan » trinh han, trinh quan, thanh phan
phan dang » phan dau, phan cong, nhan dan
dang cong » dung cong
cho manh » ho manh, chu manh, cho minh
cong dan » cong san, cong tan, huong dan
toan tai » toan tap, doanh tai, toan cao

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: cap cho manh - hanh trinh phan dang cong dan ((toan tai) OR (((toan ban) OR (van ban))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cap cho manh - hanh trinh phan dang cong dan ((toan tai) or (((toan ban) OR (van ban))))~".
• Adding a wildcard symbol may retrieve word variants: cap cho manh - hanh trinh phan dang cong dan ((toan tai) or (((toan ban) OR (van ban))))*.
