Perhaps you should try some spelling variations:
te sach » toc sach
hanh de » hanh ve, hanh kem
va hanh » van hanh, va thanh, va danh
va chat » van chat, va phat, cao chat
va cham » va tham
va nang » van nang, da nang, cam nang
luc va » duc va, tuc va, loc va
v nang » vu nang, van nang, voi nang
de cua » le cua, te cua, dieu cua
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: te sach ((v nang) OR (va nang)) xa hoi. hieu ((va cham) OR (va chat)) luc va hanh de cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((v nang) or (va nang)) xa hoi. hieu ((va cham) OR (va chat)) luc va hanh de cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach ((v nang) or (va nang)) xa hoi. hieu ((va cham) OR (va chat)) luc va hanh de cua te*.
