Perhaps you should try some spelling variations:
thanh dat » thanh san, thanh hai, thanh ha
thanh van » thanh san, thanh toan, thanh phan
cua tre » cua te, cuu tre, cua triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
tu sac » tu sach, tu cac, tu san
luc va » duc va, tuc va, loc va
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, xac va
va cao » va cac, va co, va dao

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 sac ky lang xa hoi. hieu va cao ((xuc va) OR (luc va)) ((thanh dat) OR (thanh van)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu va cao ((xuc va) or (luc va)) ((thanh dat) OR (thanh van)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu va cao ((xuc va) or (luc va)) ((thanh dat) OR (thanh van)) cua tre*.
