Perhaps you should try some spelling variations:
nhanh hai » nhanh thai, thanh hai, nhanh ha
van nhanh » van thanh, van hanh, van khanh
xuc van » duc van, luc van, vuc van
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
cua tre » cuu tre, cua triet, dua tren
su sai » su tai, su hai, su dai
cua te » cua tu
va cam » va cham, va cac, va cao
sai ky » sac ky
ve cam » ve cham, ve cac, ve cai

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: su sai ky tang xa hoi. hieu ((ve cam) OR (va cam)) xuc van nhanh hai ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky tang xa hoi. hieu ((ve cam) or (va cam)) xuc van nhanh hai ((cua tre) OR (cua te))~".
• Adding a wildcard symbol may retrieve word variants: su sai ky tang xa hoi. hieu ((ve cam) or (va cam)) xuc van nhanh hai ((cua tre) OR (cua te))*.
