Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
cua tre » cua te, cuu tre, cua triet
vai cua » dai cua, hai cua, lai cua
luc van » luoc van, luu van, duc van
xuc van » duc van, vuc van, xuc ban
ve chat » va chat, van chat
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa
sac ky » cac ky, sai ky
su sac » su sach, su cac, su xac

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