Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
hanh mai » hanh ma, hanh mau, hanh may
va triet » va thiet, va trien, ve triet
nang xa » lang xa, nang ma, mang xa
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
xuc van » duc van, luc van, vuc van
sac ky » cac ky

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