Perhaps you should try some spelling variations:
cau thuc » cau truc, cuu thuc, can thuc
hieu va » lieu va, hieu qua
thuc va » thuc vat, thuc dan, thuc day
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
lap ly » cap ly
tap ly » tam ly, tap ky
va cau » van cau, va cac, va dau
vi cua » vai cua, di cua
x hoi » xa hoi, o hoi, x ho

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((lap ly) OR (tap ly)) nang x hoi. hieu va cau thuc va hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: thuat ((lap ly) OR (tap ly)) nang x hoi. hieu va cau thuc va hanh vi cua tre*.
