Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
va triet » va thiet, va trien, ve triet
nang xa » lang xa, mang xa, ang xa
nang ma » tang ma, sang ma, nang cao
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » van hanh, va thanh, va danh
tu sai » tu bai, tu san, tu cai
sai ky » sac ky
xuc va » duc va, tuc va, luc va
dai va » mai 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: tu sai ky ((((nang xa) OR (nang ma))) OR (nang x)) hoi. hieu va cac xuc va hanh dai va triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky ((((nang xa) OR (nang ma))) or (nang x)) hoi. hieu va cac xuc va hanh dai va triet~".
• Adding a wildcard symbol may retrieve word variants: tu sai ky ((((nang xa) OR (nang ma))) or (nang x)) hoi. hieu va cac xuc va hanh dai va triet*.
