Perhaps you should try some spelling variations:
thuc day » thuc dan, thuc vat
hanh lam » thanh lap, hanh kem, hanh va
lam chau » lai chau, lam chu, lam chat
chau tre » chay tren, chau tho, cho tre
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu va » lieu va, hieu qua
thuc va » thuc vat, thuc dan
va cam » va cham, va cac, va cao
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 sach ky tang xa hoi. hieu va cam ((xuc va) OR (((thuc va) OR (thuc day)))) hanh lam chau tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky tang xa hoi. hieu va cam ((xuc va) or (((thuc va) OR (thuc day)))) hanh lam chau tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky tang xa hoi. hieu va cam ((xuc va) or (((thuc va) OR (thuc day)))) hanh lam chau tre*.
