Perhaps you should try some spelling variations:
loai roi » loi roi, toan roi, loai bo
hanh vii » hanh voi, hanh va, hanh noi
chat huu » pham huu
tieu su » thieu so
ky dang » ky nang, ky danh
lai roi » lai hoi, loi roi
su chat » su phat, du chat, so chat
tu sac » tu sach, tu cac, tu san
huu va » cuu va, tuu va
sac ky » cac ky, sai ky
cua tu » cua tuc, cua su, cua cu

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 dang ((loai roi) OR (lai roi)). tieu su chat huu va ((hanh vii) OR (hanh vi)) cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky dang ((loai roi) OR (lai roi)). tieu su chat huu va ((hanh vii) or (hanh vi)) cua tu~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky dang ((loai roi) OR (lai roi)). tieu su chat huu va ((hanh vii) or (hanh vi)) cua tu*.
