Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van thanh » ban thanh, van tuan
thanh vai » thanh hai, thanh van, thanh tai
hieu va » lieu va, hieu qua
cam duc » cam xuc, cao duc, pham duc
duc van » duc va, duc tan, duc manh
vai cua » dai cua, hai cua, lai cua
tu sach » thu sach, su sach, te sach
v nang » va nang, vu nang, van nang
ma hoi » mai hoi, xa hoi, me hoi
y nang » ky nang, ly nang, may nang
va cam » va cham, va cac, va cao

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 ((y nang) OR (v nang)) ((ma hoi) OR (ma hoa)). hieu va cam duc van thanh vai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) or (v nang)) ((ma hoi) OR (ma hoa)). hieu va cam duc van thanh vai cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (v nang)) ((ma hoi) OR (ma hoa)). hieu va cam duc van thanh vai cua triet*.
