Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
thuc va » thuc dan, thuc day
sach v » sach va, sach y, sach 2
v nang » va nang, vu nang, van nang
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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang xa hoi. hieu ve cam ((thuc va) OR (thuc vat)) hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: su sach v nang xa hoi. hieu ve cam ((thuc va) OR (thuc vat)) hanh vi cua triet*.
