Perhaps you should try some spelling variations:
thanh vi » hanh vi, thanh va, thanh ve
va thanh » gia thanh, ban thanh, va tinh
hieu ve » hieu va, hieu van
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
cam tu » cam thu, nam tu, dam tu
vi cua » vai cua, di cua
cua tu » cua tuc, cua su, cua cu
x hoi » xa hoi, o hoi, 5 hoi

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) OR (x ho)). hieu ve ((cam tu) OR (nam thu)) va thanh vi cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ((x hoi) OR (x ho)). hieu ve ((cam tu) or (nam thu)) va thanh vi cua tu~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ((x hoi) OR (x ho)). hieu ve ((cam tu) or (nam thu)) va thanh vi cua tu*.
