Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
vai cua » dai cua, hai cua, lai cua
anh vai » anh va, anh bai, anh van
vuc van » duc van, luc van, thuc van
xuc van » duc van, luc van, xuc ban
thu san » thuy san, thu ban, phu san
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
san ky » sang ky, van ky, dan ky
ve cai » va cai, ve cac, ve tai

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: thu san ky nang xa hoi. hieu ((ve cai) or (vien cac)) ((xuc van) OR (vuc van)) anh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ky nang xa hoi. hieu ((ve cai) OR (vien cac)) ((xuc van) OR (vuc van)) anh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ky nang xa hoi. hieu ((ve cai) or (vien cac)) ((xuc van) OR (vuc van)) anh vai cua tre*".
