Perhaps you should try some spelling variations:
thanh lap » thanh san, phan lap, thanh hai
cham xuc » cam xuc, chat xuc, cham soc
dang xay » dang van, van xay
hanh lai » hanh lam, hanh tai, thanh loi
cua tre » cua te, cuu tre, cua triet
va cham » va chat, va tham
hieu va » lieu va, hieu qua
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va
so sac » so sach, so dac

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 sac ky ((nang x) OR (dang xay)) hoi. hieu va cham xuc va ((hanh lai) OR (thanh lap)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sac ky ((nang x) or (dang xay)) hoi. hieu va cham xuc va ((hanh lai) OR (thanh lap)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: so sac ky ((nang x) or (dang xay)) hoi. hieu va cham xuc va ((hanh lai) OR (thanh lap)) cua tre*.
