Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
so dang » so dan, so dung, xo dang
su dang » su dung
nang xa » nang x, lang xa, nang ma
van cac » van hac, van cau, van bac
cac xuc » cam xuc, cac nuoc, chat xuc
xuc cac » xuc tac, tuc cac, xuc cam
di cua » doi cua, de cua, do cua

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((so dang) OR (su dang)) ky nang xa hoi. hieu van cac xuc cac dan ((di cua) OR (dai cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so dang) OR (su dang)) ky nang xa hoi. hieu van cac xuc cac dan ((di cua) or (dai cua)) te~".
• Adding a wildcard symbol may retrieve word variants: ((so dang) OR (su dang)) ky nang xa hoi. hieu van cac xuc cac dan ((di cua) or (dai cua)) te*.
