Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
cam thuc » am thuc, nam thuc, cam thu
thu san » thuy san, thu ban, thuat san
hieu va » hieu qua
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
phu san » phi san, thuy san

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 san) OR (phu san)) ky nang xa hoi. ((lieu va) OR (hieu va)) cam thuc va hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu san) OR (phu san)) ky nang xa hoi. ((lieu va) or (hieu va)) cam thuc va hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((thu san) OR (phu san)) ky nang xa hoi. ((lieu va) or (hieu va)) cam thuc va hanh vai cua tre*.
