Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
cua triet » cua viet, su triet, va triet
may nang » may nong, ky nang, cam nang
van nang » van quang, van ban, van dong
thanh ve » hanh ve, thanh va, thanh vien
tu sach » thu sach, su sach, te sach
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
xuc van » duc van, luc van, vuc van
ve cua » le cua, de cua, te cua

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 sach ((may nang) OR (van nang)) xa hoi. hieu va cac xuc van thanh ve cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach ((may nang) or (van nang)) xa hoi. hieu va cac xuc van thanh ve cua triet*.
