Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
van hanh » van thanh, ban hanh, van anh
cua tre » cua te, cuu tre, cua triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
tai cua » thai cua, tai cuc, tri cua
xa duc » xuan duc
su sac » su sach, su cac, su xac
ha duc » ho duc, ha dac, hoa duoc
sac ky » cac ky, sai ky
ha tuc » ha thuc, va tuc, thai tuc

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 lang xa hoi. hieu va ((ha tuc) OR (((ha duc) OR (xa duc)))) van hanh tai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky lang xa hoi. hieu va ((ha tuc) or (((ha duc) OR (xa duc)))) van hanh tai cua tre~".
• Adding a wildcard symbol may retrieve word variants: su sac ky lang xa hoi. hieu va ((ha tuc) or (((ha duc) OR (xa duc)))) van hanh tai cua tre*.
