Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
dang mam » dang nam, dang mau, dang mat
vai cua » dai cua, hai cua, lai cua
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
mam hoi » mam hoai, nam hoi, mai hoi
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky
xac va » tac va, ac va, bac va
luc va » duc va, tuc va, loc 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: toc ((sac ky) OR (sai ky)) dang mam hoi. hieu ve cham ((xac va) OR (luc va)) thanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sac ky) OR (sai ky)) dang mam hoi. hieu ve cham ((xac va) or (luc va)) thanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc ((sac ky) OR (sai ky)) dang mam hoi. hieu ve cham ((xac va) or (luc va)) thanh vai cua tre*.
