Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
nang xa » lang xa, nang ma, mang xa
sai ky » sac ky
xuc va » duc va, tuc va, luc va
tu sai » tu bai, tu san, tu cai
ma ve » mat ve, mua ve, va ve
ca ve » ca va, va ve

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 sai ky ((nang xa) OR (nang x)) hoi. hieu va cac xuc va thanh ((ma ve) OR (ca ve)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky ((nang xa) or (nang x)) hoi. hieu va cac xuc va thanh ((ma ve) OR (ca ve)) triet~".
• Adding a wildcard symbol may retrieve word variants: tu sai ky ((nang xa) or (nang x)) hoi. hieu va cac xuc va thanh ((ma ve) OR (ca ve)) triet*.
