Perhaps you should try some spelling variations:
van xanh » van anh, van hanh, van manh
cua tre » cua te, cuu tre, cua triet
xanh di » danh di, vanh dai, xanh tai
nang xa » nang x, lang xa, nang ma
va cham » va chat
va tham » van tham, va thanh, va thuat
di cua » dai cua, doi cua, de cua
oc van » hoc van, luoc van, quoc van
tu can » tu ban, thu canh

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) OR (va tham)) 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) OR (va tham)) 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) OR (va tham)) oc van xanh di cua tre*".
