Perhaps you should try some spelling variations:
cham loc » cham soc, chon loc, hau loc
hieu van » hieu va, thien van, lieu va
doi cua » dai cua, hoi cua
dan doi » dan hoi, dan toi, van doi
te sach » toc sach
cua tre » cua te, cuu tre, cua triet
v nang » va nang, vu nang, van nang
y nang » ky nang, ly nang, may nang
cham o » cham soc
ca dan » cac dan, ca dao

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 ((y nang) OR (v nang)) xa hoi. hieu van ((cham loc) OR (cham o)) ca dan doi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (v nang)) xa hoi. hieu van ((cham loc) or (cham o)) ca dan doi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) OR (v nang)) xa hoi. hieu van ((cham loc) or (cham o)) ca dan doi cua tre*.
