Perhaps you should try some spelling variations:
thai cua » than cua, tai cuc, tri cua
ban hanh » ban hang
van hanh » van thanh, van anh, van ban
cua tre » cua te, cuu tre, cua triet
cac vuc » cac nuoc, cac vung, cac cuoc
hieu va » lieu va, hieu qua
nang co » nang cao, nang doc, nang noi
co lai » con lai, o lai, co dai
tu san » thu san, tu ban, tu can
tu bat » tu ban, tu dat

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 co lai. hieu va cac vuc ((van hanh) OR (ban hanh)) thai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu bat) or (tu san)) ky nang co lai. hieu va cac vuc ((van hanh) OR (ban hanh)) thai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu bat) or (tu san)) ky nang co lai. hieu va cac vuc ((van hanh) OR (ban hanh)) thai cua tre*.
