Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
thu sac » thu sach, thu xac, thu dac
vai cua » dai cua, hai cua, lai cua
va danh » va dinh, va dan, va hanh
cua tre » cua te, cuu tre, cua triet
hieu va » lieu va, hieu qua
thu san » thuy san, thu ban, phu san
cac lo » cac lop, cac co, cac bo
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: ((thu sac) OR (thu san)) ky nang x hoi. hieu va cac lo ((va danh) OR (va thanh)) vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sac) OR (thu san)) ky nang x hoi. hieu va cac lo ((va danh) or (va thanh)) vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((thu sac) OR (thu san)) ky nang x hoi. hieu va cac lo ((va danh) or (va thanh)) vai cua tre*.
