Perhaps you should try some spelling variations:
va triet » va thiet, ve triet, cua triet
trinh su » trinh tu, trinh san, trinh cau
va trien » va truyen, va thiet, va tuyen
thu sac » thu sach, thu san, thu xac
hieu ve » hieu va, hieu van
tinh su » hinh su, tinh tu, dinh su
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang x ho. hieu ve cam xuc va ((tinh su) OR (trinh su)) ((va triet) or (va trien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang x ho. hieu ve cam xuc va ((tinh su) OR (trinh su)) ((va triet) OR (va trien)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang x ho. hieu ve cam xuc va ((tinh su) OR (trinh su)) ((va triet) or (va trien))".
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang x ho. hieu ve cam xuc va ((tinh su) OR (trinh su)) ((va triet) or (va trien))*.
