Perhaps you should try some spelling variations:
sach bai » sach dao, cac bai, sach xa
qua phat » qua nhat, qua phan, que phat
ban hang » ngan hang
phat xuc » chat xuc, phat xuat, phap xu
xuc ban » duc ban, cuc ban, quoc ban
anh bai » danh bat, hinh bai
di cua » dai cua, doi cua, de cua
vi cua » vai cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky

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 sac ky ((anh bai) OR (sach bai)) hoi. hieu qua phat xuc ban hang ((vi cua) OR (di cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((anh bai) OR (sach bai)) hoi. hieu qua phat xuc ban hang ((vi cua) or (di cua)) te~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((anh bai) OR (sach bai)) hoi. hieu qua phat xuc ban hang ((vi cua) or (di cua)) te*.
