Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
hanh tri » thanh tri, hanh trinh, hanh triet
hanh tai » thanh tai, hang tai, han tai
hieu ve » hieu va
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
cua cu » cua chu, cua cau, cua su
x hoi » xa hoi, o hoi, x ho

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 nang x hoi. ((hieu ve) OR (hieu van)) phan tu va ((hanh tri) OR (hanh tai)) cua cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang x hoi. ((hieu ve) or (hieu van)) phan tu va ((hanh tri) OR (hanh tai)) cua cu~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang x hoi. ((hieu ve) or (hieu van)) phan tu va ((hanh tri) OR (hanh tai)) cua cu*.
