Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
tan thanh » tran thanh, tang thanh, toan thanh
vien cac » vien bach, vien dai, vien da
cua tre » cua te, cuu tre, cua triet
vai cua » dai cua, hai cua, lai cua
nang xa » nang x, lang xa, nang ma
su sac » su sach, su cac
su xac » pu xac, su cac
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) OR (su xac)) ky nang xa hoi. hieu ((ve cac) or (vien cac)) duc tan thanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky nang xa hoi. hieu ((ve cac) OR (vien cac)) duc tan thanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky nang xa hoi. hieu ((ve cac) or (vien cac)) duc tan thanh vai cua tre*".
