Perhaps you should try some spelling variations:
ky tang » ky nang, kho tang, ky trong
ky dang » ky nang, ky danh
hieu ve » hieu va, hieu van
xuc van » duc van, luc van, vuc van
xuc ban » duc ban, cuc ban, quoc ban
anh hai » lanh hai, manh hai, anh thai
hai cua » thai cua, dai cua, hoi cua
su sac » su sach, su cac, su xac
ve cam » ve cham, ve cac, va cam
cua te » cua tu

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: su sac ((ky tang) OR (ky dang)) xa hoi. hieu ve cam ((xuc van) OR (xuc ban)) anh hai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky tang) or (ky dang)) xa hoi. hieu ve cam ((xuc van) OR (xuc ban)) anh hai cua te~".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky tang) or (ky dang)) xa hoi. hieu ve cam ((xuc van) OR (xuc ban)) anh hai cua te*.
