Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, le thanh
ban hanh » ban hang
te sach » toc sach
va tinh » may tinh
cua tre » cua te, cuu tre, cua triet
sach ty » sach y, sach tu, sach thu
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
ve cac » va cac, vien cac
di cua » dai cua, doi cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty nang xa hoi. hieu ve cac xuc ((((va thanh) OR (va tinh))) or (ban hanh)) di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang xa hoi. hieu ve cac xuc ((((va thanh) OR (va tinh))) OR (ban hanh)) di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang xa hoi. hieu ve cac xuc ((((va thanh) OR (va tinh))) or (ban hanh)) di cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty nang xa hoi. hieu ve cac xuc ((((va thanh) OR (va tinh))) or (ban hanh)) di cua tre*.
