Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
cao hoi » cau hoi, co hoi, cao hoc
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
xuc ban » cuc ban, quoc ban, xuat ban
duc ban » duc tan, duc van, dua ban
cua tre » cuu tre, cua triet, dua tren
tu sai » tu bai, tu san, tu cai
sai ky » sac ky
cua te » cua tu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky nang cao hoi. hieu ve cham ((xuc ban) or (duc ban)) hanh vai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky nang cao hoi. hieu ve cham ((xuc ban) OR (duc ban)) hanh vai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky nang cao hoi. hieu ve cham ((xuc ban) or (duc ban)) hanh vai ((cua tre) OR (cua te))*".
