Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
va thanh » gia thanh, va tinh, le thanh
tu sach » thu sach, su sach, te sach
ly nang » ky nang, ly hang, ly vang
hieu ve » hieu va, hieu van
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, v nang, may nang
ve cam » ve cham, ve cac, va cam
vi cua » vai cua, di cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y nang) or (ly nang)) xa hoi. hieu ve cam xuc ((va thanh) OR (ban thanh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (ly nang)) xa hoi. hieu ve cam xuc ((va thanh) OR (ban thanh)) vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) or (ly nang)) xa hoi. hieu ve cam xuc ((va thanh) OR (ban thanh)) vi cua tre*".
