Perhaps you should try some spelling variations:
tham thuc » pham thuc, tam thuc, thai thuc
nham thuc » nhan thuc, nam thuc, nham thu
cua triet » cua viet, su triet, va triet
thu sach » tu sach, thuat sach, thuoc sach
hanh vai » hanh vi, hanh va, hanh tai
sach ki » sach kinh, sach bai, sach kem

lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
vai cua » dai cua, hai cua, lai cua

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: thu sach ki lang xa hoi. hieu ve ((tham thuc) OR (nham thuc)) va hanh vai cua triet~.
• Adding a wildcard symbol may retrieve word variants: thu sach ki lang xa hoi. hieu ve ((tham thuc) or (nham thuc)) va hanh vai cua triet*.
