Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, doanh tai
van thanh » ban thanh, van tuan
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
xuc van » duc van, luc van, vuc van
su sac » su cac, su xac
ve cam » ve cham, ve cac, va cam
tai va » thai va, mai va, tri va
x hoi » xa hoi, o hoi, 5 hoi
thiet » thieu

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) OR (su sach)) ky nang ((x hoi) OR (x ho)). hieu ve cam xuc van thanh tai va thiet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su sach)) ky nang ((x hoi) OR (x ho)). hieu ve cam xuc van thanh tai va thiet~".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su sach)) ky nang ((x hoi) OR (x ho)). hieu ve cam xuc van thanh tai va thiet*.
