Perhaps you should try some spelling variations:
thanh dai » thanh hai, thanh tai, thanh dat
cuu tre » cau tren, cau treo
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
cua tre » cua te, cua triet, dua tren
tu sac » tu sach, tu cac, tu san
tuc va » thuc va, truc va, tuc xa
sac ky » cac ky, sai ky
xuc va » duc va, luc va, xac 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 sac ky lang xa hoi. hieu ve chat ((xuc va) OR (tuc va)) thanh dai ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu ve chat ((xuc va) or (tuc va)) thanh dai ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu ve chat ((xuc va) or (tuc va)) thanh dai ((cua tre) OR (cuu tre))*.
