Perhaps you should try some spelling variations:
nhanh lang » nhanh quang, nhanh thang, nhan dang
hanh dung » thanh dung, anh dung, hanh dong
luan ung » luan hung, luon ung, luan chung
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
va tinh » may tinh
thi cao » thai cao, thi hao, thi bao
ho va » ho van, nho va, tho va

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 va tinh - ((hanh dung) OR (nhanh lang)) luan ung ((cong dan) OR (cong tan)) thi cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho va tinh - ((hanh dung) or (nhanh lang)) luan ung ((cong dan) OR (cong tan)) thi cao~".
• Adding a wildcard symbol may retrieve word variants: ho va tinh - ((hanh dung) or (nhanh lang)) luan ung ((cong dan) OR (cong tan)) thi cao*.
