Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
tay lang » tai lang, tay tang, tay quang
danh vai » danh sai, danh va, doanh van
va danh » va dinh, va dan, va hanh
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
ky dang » ky nang, ky danh
cac xuc » cam xuc, cac nuoc, chat xuc
xuc va » duc va, tuc va, luc va
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((tay lang) or (ky dang)) xa hoi. hieu ve cac xuc va danh vai ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((tay lang) OR (ky dang)) xa hoi. hieu ve cac xuc va danh vai ((cua triet) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((tay lang) or (ky dang)) xa hoi. hieu ve cac xuc va danh vai ((cua triet) OR (va triet))*".
