Perhaps you should try some spelling variations:
thanh lap » thanh san, phan lap, thanh hai
ban thanh » ban hanh, ban hang
chat xuc » chat huu, cam xuc, chao xu
va triet » va thiet, ve triet, cua triet
va trien » va truyen, va thiet, va tuyen
so sach » so sanh, bo sach, co sach
ty nang » ty xang, ty hang, ly nang
va chat » van chat, va phat, cao chat
xuc ban » duc ban, cuc ban, quoc ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ((ty nang) or (ky nang)) xa hoi. lieu va chat xuc ban thanh lap ((va triet) OR (va trien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ((ty nang) OR (ky nang)) xa hoi. lieu va chat xuc ban thanh lap ((va triet) OR (va trien))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ((ty nang) or (ky nang)) xa hoi. lieu va chat xuc ban thanh lap ((va triet) OR (va trien))*".
