Perhaps you should try some spelling variations:
hieu van » thien van, lieu va
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
hanh va » hang va, hanh vi
tu cai » tu cac, tu can, tu bai
cai ky » cao ky, cac ky, cam ky
xuc va » duc va, tuc va, luc va
va cua » va chua, via cua, ca cua
cua te » cua tu
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: tu cai ky nang x hoi. ((((hieu ve) OR (hieu va))) or (hieu van)) cam xuc va hanh va cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cai ky nang x hoi. ((((hieu ve) OR (hieu va))) OR (hieu van)) cam xuc va hanh va cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cai ky nang x hoi. ((((hieu ve) OR (hieu va))) or (hieu van)) cam xuc va hanh va cua te*".
