Perhaps you should try some spelling variations:
toc sach » doc sach, thuoc sach, nuoc sach
thu pham » thuc pham, thu phan, thuc phan
hoc sach » hoc sinh, hoc cac, hoc anh
hanh lam » thanh lap, hanh kem, hanh va
lam cua » nam cua, lam chat
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
tu pham » su pham, tu phat, tu cham
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet

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: ((toc sach) OR (hoc sach)) ky nang xa hoi. hieu ((tu pham) OR (thu pham)) thuc va hanh lam cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) or (hoc sach)) ky nang xa hoi. hieu ((tu pham) OR (thu pham)) thuc va hanh lam cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) or (hoc sach)) ky nang xa hoi. hieu ((tu pham) OR (thu pham)) thuc va hanh lam cua tre*.
