Perhaps you should try some spelling variations:
thieu nang » thien nang, thieu khang, thieu quang
cham xuc » cam xuc, chat xuc, cham soc
van doan » van doanh, van toan, van hoan
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
xuc van » duc van, luc van, vuc van
van cua » vang cua, ban cua, nan cua
dan cua » dan ca, ban cua, dai 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 thieu nang xa hoi. ((hieu ve) OR (lieu va)) cham xuc van doan ((van cua) OR (dan cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thieu nang xa hoi. ((hieu ve) or (lieu va)) cham xuc van doan ((van cua) OR (dan cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach thieu nang xa hoi. ((hieu ve) or (lieu va)) cham xuc van doan ((van cua) OR (dan cua)) tre*.
