Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
cua triet » cua viet, va triet
van thanh » ban thanh, van tuan
su triet » su viet, su tien, ve triet
xuc van » duc van, luc van, xuc ban
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
ky lang » ky dang, ky tang, tay lang
ve cac » va cac, vien cac
su sac » su sach, su cac, su xac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ((ky lang) OR (ky nang)) xa hoi. hieu ve cac xuc van thanh vai ((cua triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky lang) OR (ky nang)) xa hoi. hieu ve cac xuc van thanh vai ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky lang) OR (ky nang)) xa hoi. hieu ve cac xuc van thanh vai ((cua triet) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky lang) OR (ky nang)) xa hoi. hieu ve cac xuc van thanh vai ((cua triet) or (su triet))*.
