Perhaps you should try some spelling variations:
cham xuc » chat xuc, cham soc, pham duc
cau tren » dau tren, ca tren, cau treo
bo sach » co sach, hoc sach
va hanh » van hanh, va thanh, va danh
hanh va » hang va, hanh vi
cu tren » tu tren, dua tren
y nang » ky nang, ly nang, v nang
x hoi » xa hoi, o hoi, x ho

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: bo sach y nang x hoi. lieu va ((cham xuc) OR (cam xuc)) va hanh va ((cau tren) OR (cu tren))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "bo sach y nang x hoi. lieu va ((cham xuc) or (cam xuc)) va hanh va ((cau tren) OR (cu tren))~".
• Adding a wildcard symbol may retrieve word variants: bo sach y nang x hoi. lieu va ((cham xuc) or (cam xuc)) va hanh va ((cau tren) OR (cu tren))*.
