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

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