Perhaps you should try some spelling variations:
hanh tri » thanh tri, hanh tai, hanh trinh
van hanh » van thanh, ban hanh, van anh
cua tre » cua te, cuu tre, cua triet
xuc van » duc van, luc van, vuc van
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
ve cac » va cac, vien cac
tu bat » tu ban, tu dat
co lai » con lai, o lai, co loi
tu san » thu san, tu ban, tu can
co dai » co dan, do dai

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