Perhaps you should try some spelling variations:

hieu va » lieu va, hieu qua
va cham » va chat, va tham
soc van » hoc van, sac van, soc dan
xanh di » danh di, vanh dai, xanh tai
cua tre » cua te, cuu tre, cua triet
tu can » tu ban, thu canh
oc van » hoc van, luoc van, quoc van
di cua » dai cua, doi cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cac) or (tu can)) ky nang xa hoi. hieu va cham ((soc van) OR (oc van)) xanh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cac) OR (tu can)) ky nang xa hoi. hieu va cham ((soc van) OR (oc van)) xanh di cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cac) or (tu can)) ky nang xa hoi. hieu va cham ((soc van) OR (oc van)) xanh di cua tre*".
