Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
tu sach » thu sach, su sach, te sach
va cham » va chat, va tham
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
ve cham » ve chat, vu cham, ve chim
y nang » ky nang, ly nang, v nang
ve cam » ve cac, va cam, ve cai
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang x hoi. hieu ((((ve cam) OR (ve cham))) or (va cham)) duc va hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x hoi. hieu ((((ve cam) OR (ve cham))) OR (va cham)) duc va hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. hieu ((((ve cam) OR (ve cham))) or (va cham)) duc va hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. hieu ((((ve cam) OR (ve cham))) or (va cham)) duc va hanh vai cua te*.
