Perhaps you should try some spelling variations:
may trinh » may tinh, lap trinh, quy trinh
toc sach » hoc sach, doc sach, thuoc sach
tay hoi » tay ho, tao hoi, tay thai
sach ky » sac ky, sach y, sach ty
xuc may » xuc hay, truc may, phuc may

hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam
ky van » ly van, ty van, ky va
ve cua » le cua, de cua, ve cum
te cua » tue cua, le cua, de 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: toc sach ky van ((xay hoi) OR (tay hoi)). hieu ve cam xuc may trinh ((ve cua) OR (te cua)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky van ((xay hoi) OR (tay hoi)). hieu ve cam xuc may trinh ((ve cua) or (te cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: toc sach ky van ((xay hoi) OR (tay hoi)). hieu ve cam xuc may trinh ((ve cua) or (te cua)) triet*.
