Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
tu sac » tu cac, tu san, tu bac
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky nang xa hoi. hieu ve cam xuc va hanh vi ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky nang xa hoi. hieu ve cam xuc va hanh vi ((cua tre) or (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu sach)) ky nang xa hoi. hieu ve cam xuc va hanh vi ((cua tre) or (cuu tre))*.
