Perhaps you should try some spelling variations:
thanh dat » thanh san, thanh hai, thanh van
hieu ve » hieu va, hieu van
dat cua » dai cua, day cua, mat cua
xuc van » duc van, luc van, vuc van
ve cham » va cham, ve chat, vu cham
cua tre » cua te, cuu tre, cua triet
lang ha » long ha
tang ma » mang may, tang van
sai ky » sac ky
tu sai » tu bai, tu san, tu cai

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 ((tang ma) OR (lang ha)) hoi. hieu ve cham ((xuc van) OR (duc va)) thanh dat cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sai ky ((tang ma) or (lang ha)) hoi. hieu ve cham ((xuc van) or (duc va)) thanh dat cua tre*.
