Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
cham xuc » cam xuc, chat xuc, cham soc
hanh doi » thanh doi, hanh noi, hang doi
nang xa » nang x, lang xa, nang ma
hieu ve » hieu van
doi cua » dai cua, hoi cua
hieu va » hieu qua
sach ky » sac ky, sach y, sach ty
va hanh » van hanh, va thanh, va danh
cua te » cua tu
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: thuat sach ky nang xa hoi. ((hieu ve) OR (((hieu va) OR (lieu va)))) cham xuc va hanh doi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ky nang xa hoi. ((hieu ve) or (((hieu va) OR (lieu va)))) cham xuc va hanh doi cua te~".
• Adding a wildcard symbol may retrieve word variants: thuat sach ky nang xa hoi. ((hieu ve) or (((hieu va) OR (lieu va)))) cham xuc va hanh doi cua te*.
