Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
va triet » va thiet, va trien, ve triet
va thanh » gia thanh, ban thanh, va tinh
nang xa » lang xa, nang ma, mang xa
cac xuc » cam xuc, cac nuoc, chat xuc
hieu va » lieu va, hieu qua
dai va » mai va
xuc va » duc va, tuc va, luc va
tu sai » tu san, tu cai, tu lai
tu bai » tu ban, tu bat, te bai

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