Perhaps you should try some spelling variations:
hanh thai » nhanh thai, hinh thai, hanh tai
chat xuc » chat huu, cam xuc, chao xu
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
va hanh » van hanh, va thanh, va danh
cua tre » cuu tre, cua triet, dua tren
y sang » _ sang, duy sang
xuc va » duc va, tuc va, luc va
cua te » cua tu

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 y sang ((ma hoa) OR (xa hoi)). hieu ve chat xuc va hanh thai ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y sang ((ma hoa) or (xa hoi)). hieu ve chat xuc va hanh thai ((cua tre) OR (cua te))~".
• Adding a wildcard symbol may retrieve word variants: tu sach y sang ((ma hoa) or (xa hoi)). hieu ve chat xuc va hanh thai ((cua tre) OR (cua te))*.
