Perhaps you should try some spelling variations:
van hanh » van thanh, van anh, van ban
ban hanh » ban hang
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
cam luc » cam xuc, cau luc
cua tre » cua te, cuu tre, cua triet
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
de cua » le cua, te cua, dieu cua

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang xa hoi. hieu ve cam luc ((van hanh) OR (ban hanh)) de cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sac ky lang xa hoi. hieu ve cam luc ((van hanh) OR (ban hanh)) de cua tre*.
