Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
dang xay » dang van, van xay
va thanh » gia thanh, ban thanh, va tinh
so sach » so sanh, bo sach, co sach
tap cua » tap quan, tiep cua
lap cua » lai cua, lam cua, ap cua
va cham » va chat, va tham
sach ky » sac ky, sach y, sach ty
hieu va » lieu va, hieu qua
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: so sach ky ((nang x) OR (dang xay)) hoi. hieu va cham xuc va thanh ((lap cua) OR (tap cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky ((nang x) or (dang xay)) hoi. hieu va cham xuc va thanh ((lap cua) OR (tap cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: so sach ky ((nang x) or (dang xay)) hoi. hieu va cham xuc va thanh ((lap cua) OR (tap cua)) tre*.
