Perhaps you should try some spelling variations:
van nang » van quang, van ban, van dong
hanh doi » thanh doi, hanh noi, hang doi
bo sach » co sach, hoc sach
va cham » va chat, va tham
va hanh » van hanh, va thanh, va danh
doi cua » dai cua, hoi cua
y nang » ky nang, ly nang, v nang
va cam » va cac, va cao, va cai
xuc va » duc va, tuc va, luc va
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) OR (van nang)) x hoi. lieu ((va cam) OR (va cham)) xuc va hanh doi cua vat~.
• Adding a wildcard symbol may retrieve word variants: bo sach ((y nang) or (van nang)) x hoi. lieu ((va cam) or (va cham)) xuc va hanh doi cua vat*.
