Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
va hang » van hang, va lang, va hanh
va nang » van nang, da nang, cam nang
hai cuu » hai cua, hai chu, hai cuc
cuu tre » cua tre, cau tren, cau treo
tu van » tu va
ve cac » va cac, vien cac
va cam » va cham, va cac, va cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu van ky nang xa hoi. hieu ((ve cac) or (va cam)) tuc ((va hang) OR (va nang)) hai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky nang xa hoi. hieu ((ve cac) OR (va cam)) tuc ((va hang) OR (va nang)) hai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky nang xa hoi. hieu ((ve cac) or (va cam)) tuc ((va hang) OR (va nang)) hai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu van ky nang xa hoi. hieu ((ve cac) or (va cam)) tuc ((va hang) OR (va nang)) hai cuu tre*.
