Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
thanh vai » thanh hai, thanh van, thanh tai
vien cac » vien bach, vien dai, vien da
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, mang xa
vai cua » dai cua, hai cua, lai cua
nang ma » tang ma, sang ma, nang cao
xuc van » duc van, luc van, xuc ban
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cac » va cac

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

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