Perhaps you should try some spelling variations:
sach thuc » cach thuc, sach thu, sach thue
cham xuc » cam xuc, chat xuc, cham soc
ban hanh » ban hang
te sach » toc sach
cua tre » cua te, cuu tre, cua triet
hanh de » hanh ve, hanh kem
xuc ban » duc ban, cuc ban, quoc ban
vu cham » va cham, vu kham, tu cham
hieu vu » hieu va, hieu ve, hieu su
hanh x » hanh xu, hanh y, anh x
cua tu » cua tuc, cua su, cua cu

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 thuc ((hanh x) OR (hanh _)) hoi. hieu vu cham xuc ban hanh de ((cua tre) OR (cua tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thuc ((hanh x) OR (hanh _)) hoi. hieu vu cham xuc ban hanh de ((cua tre) or (cua tu))~".
• Adding a wildcard symbol may retrieve word variants: te sach thuc ((hanh x) OR (hanh _)) hoi. hieu vu cham xuc ban hanh de ((cua tre) or (cua tu))*.
