Perhaps you should try some spelling variations:
ban hanh » ban hang
tu sach » thu sach, su sach, te sach
ky lang » ky dang, ky tang, tay lang
cac xuc » cam xuc, cac nuoc, chat xuc
xuc ban » duc ban, cuc ban, quoc ban
ha hoi » hoa hoi, ha noi, xa hoi
vi cua » vai cua
di cua » dai cua, doi 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: tu sach ((ky lang) OR (ky nang)) ha hoi. lieu va cac xuc ban hanh ((vi cua) OR (di cua)) tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach ((ky lang) or (ky nang)) ha hoi. lieu va cac xuc ban hanh ((vi cua) or (di cua)) tre*.
