Perhaps you should try some spelling variations:
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, cua triet
sinh y » sinh ly
y nang » ky nang, ly nang, v nang
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.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc sinh y nang x hoi. ((hieu ve) or (lieu va)) cam xuc ((va hanh) OR (va danh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sinh y nang x hoi. ((hieu ve) OR (lieu va)) cam xuc ((va hanh) OR (va danh)) vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sinh y nang x hoi. ((hieu ve) or (lieu va)) cam xuc ((va hanh) OR (va danh)) vi cua tre*".
