Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
vai cua » dai cua, hai cua, lai cua
thu ban » thu hang
anh vai » anh va, anh bai, anh van
nang xa » nang x, lang xa, nang ma
van anh » van thanh, tuan anh, van minh
duc van » duc va, duc tan, duc manh
tu ban » te ban
ve cac » va cac, vien cac
ve cai » va cai, ve tai, ve cau

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 ban) OR (thu ban)) ky nang xa hoi. hieu ((ve cai) OR (ve cac)) duc van anh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu ban) OR (thu ban)) ky nang xa hoi. hieu ((ve cai) or (ve cac)) duc van anh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu ban) OR (thu ban)) ky nang xa hoi. hieu ((ve cai) or (ve cac)) duc van anh vai cua tre*.
