Perhaps you should try some spelling variations:
pham chuc » pham duc, pham huu, kham chua
doan day » doan dau, doan hay, dan day
te sach » toc sach
hieu ve » hieu va, hieu van
day cua » dai cua
va doan » va doanh, van doan, va dan
chuc va » thuc va, thuc vat
cua tre » cua te, cuu tre, cua triet
sach ky » sac ky, sach y, sach ty
hieu vu » hieu va, hieu su, dieu vu
ma hoi » mai hoi, xa hoi, me hoi

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: te sach ky nang ((ma hoi) OR (ma hoa)). ((hieu vu) OR (hieu ve)) pham chuc va doan day cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ((ma hoi) or (ma hoa)). ((hieu vu) OR (hieu ve)) pham chuc va doan day cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ((ma hoi) or (ma hoa)). ((hieu vu) OR (hieu ve)) pham chuc va doan day cua tre*.
