Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh tai, thanh oai
thanh van » thanh san, thanh toan, thanh phan
hieu van » hieu va, thien van, lieu va
cua tre » cua te, cuu tre, cua triet
xuc van » duc van, luc van, xuc ban
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
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 lang xa hoi. ((hieu ve) OR (hieu van)) cac xuc van ((thanh vai) OR (thanh van)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky lang xa hoi. ((hieu ve) OR (hieu van)) cac xuc van ((thanh vai) or (thanh van)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: su sac ky lang xa hoi. ((hieu ve) OR (hieu van)) cac xuc van ((thanh vai) or (thanh van)) cua tre*.
