Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
van hanh » van thanh, ban hanh, van anh
cac nuoc » cap nuoc, hoc nuoc, dat nuoc
hieu ve » hieu va, hieu van
cac xuc » cam xuc, chat xuc, cac cuoc
tu bat » tu ban, tu dat
nang o » nang co, nang ho, nang ro
tu san » thu san, tu ban, tu can
cuc te » cua te, cuc thue, cuc tieu
o lai » o lao

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: ((tu bat) OR (tu san)) ky nang o lai. hieu ve ((cac xuc) OR (cac nuoc)) van hanh tai cuc te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu bat) or (tu san)) ky nang o lai. hieu ve ((cac xuc) OR (cac nuoc)) van hanh tai cuc te~".
• Adding a wildcard symbol may retrieve word variants: ((tu bat) or (tu san)) ky nang o lai. hieu ve ((cac xuc) OR (cac nuoc)) van hanh tai cuc te*.
