Perhaps you should try some spelling variations:
hanh giau » thanh gian, danh gia, anh giao
thu sach » tu sach, thuat sach, thuoc sach
dang xay » dang van
va thanh » gia thanh, ban thanh, va tinh
giau cua » gian cua, gia cua, dieu cua
cua viet » ca viet, hoa viet, cua vat
sach ty » sach y, sach tu, sach thu
thuy va » thuy van, thuc va, thue va
va hanh » van hanh, va danh, ban hanh

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 ty ((dang xay) OR (van xay)) hoi. lieu va thanh thuy va hanh giau cua viet~.
• Adding a wildcard symbol may retrieve word variants: thu sach ty ((dang xay) or (van xay)) hoi. lieu va thanh thuy va hanh giau cua viet*.
