Perhaps you should try some spelling variations:
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach y, sach vay
ve cac » va cac, vien cac
sach 2 » sach y
xuc va » duc va, tuc va, luc va
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: tu ((sach v) OR (sach 2)) nang xa hoi. hieu ve cac xuc va hanh ((vi cua) OR (vai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach v) or (sach 2)) nang xa hoi. hieu ve cac xuc va hanh ((vi cua) OR (vai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach v) or (sach 2)) nang xa hoi. hieu ve cac xuc va hanh ((vi cua) OR (vai cua)) tre*.
