Perhaps you should try some spelling variations:
thuat lap » thuat lanh, thuat xay, thuat bai
ly nang » ky nang, ly hang, ly vang
hieu va » lieu va, hieu qua
truc va » thuc va, thuc vat, trung va
va hanh » van hanh, va thanh, va danh
vai cua » dai cua, hai cua, lai cua
ly van » le van, ly va, ly von
va cau » van cau, va cac, va dau
vi cua » di cua
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: thuat lap ((ly nang) OR (ly van)) x hoi. hieu va cau truc va hanh ((vi cua) OR (vai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lap ((ly nang) or (ly van)) x hoi. hieu va cau truc va hanh ((vi cua) OR (vai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: thuat lap ((ly nang) or (ly van)) x hoi. hieu va cau truc va hanh ((vi cua) OR (vai cua)) tre*.
