Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
va cham » va chat, va tham
xa hanh » xa thanh, xa khanh, va hanh
ve cam » ve cham, ve cac, va cam
vi cua » vai cua, di 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: tu sach ty xang xa hoi. hieu ((ve cam) OR (va cham)) tuc xa hanh vi cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach ty xang xa hoi. hieu ((ve cam) or (va cham)) tuc xa hanh vi cua triet*.
