Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
cam tuc » cam xuc, cam tu, nam thuc
van tai » von tai, van tuan
han tai » hang tai, nhan tai, toan tai
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
te sac » te sach, te cac, te san
tuc va » thuc va, truc va, tuc xa
tu san » thu san, tu ban, tu can
va cam » va cham, va cac, va cao

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: ((te sac) OR (tu san)) ky lang xa hoi. hieu va cam tuc va ((han tai) OR (van tai)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (tu san)) ky lang xa hoi. hieu va cam tuc va ((han tai) OR (van tai)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (tu san)) ky lang xa hoi. hieu va cam tuc va ((han tai) OR (van tai)) cua tre*.
