Perhaps you should try some spelling variations:
sach doi » sach hoi, sach moi, sach dao
doi nang » dai nang, hoi nang, voi nang
hanh tai » thanh tai, hang tai, han tai
cham xuc » cam xuc, chat xuc, cham soc
tu sach » thu sach, su sach, te sach
hanh va » hang va
cuu tre » cua tre, cau tren, cau treo
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
xuc va » duc va, tuc va, luc va

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 doi nang xa hoi. hieu ve cham xuc va ((hanh tai) OR (((hanh va) OR (hanh vi)))) cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach doi nang xa hoi. hieu ve cham xuc va ((hanh tai) or (((hanh va) OR (hanh vi)))) cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach doi nang xa hoi. hieu ve cham xuc va ((hanh tai) or (((hanh va) OR (hanh vi)))) cuu tre*.
