Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
xuc cam » phuc cam
cam dan » cac dan, ca dan, nam dan
vai cua » dai cua, hai cua, lai cua
su sai » su tai, su hai, su mai
su dai » sau dai, si dai, su tai
vi cua » di 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: ((su sai) OR (su dai)) ky nang xa hoi. hieu van cam xuc cam dan ((vi cua) OR (vai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sai) OR (su dai)) ky nang xa hoi. hieu van cam xuc cam dan ((vi cua) or (vai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sai) OR (su dai)) ky nang xa hoi. hieu van cam xuc cam dan ((vi cua) or (vai cua)) tre*.
