Perhaps you should try some spelling variations:
tinh bai » tinh bac, tinh hai, hinh bai
bai cua » ban cua, dai cua, bai ca
va tinh » may tinh
van cam » van lam, van cau, van dam
thu xac » thau xay
xac ky » cac ky, sac ky, bac ky
xuc va » duc va, tuc va, luc va
cua te » cua tu
o hoc » co hoc, mo hoc, so hoc
o hoi » co hoi, o hai, o hoa

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu xac ky nang ((o hoi) OR (o hoc)). hieu ((van cam) or (van nam)) xuc va tinh bai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu xac ky nang ((o hoi) OR (o hoc)). hieu ((van cam) OR (van nam)) xuc va tinh bai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu xac ky nang ((o hoi) OR (o hoc)). hieu ((van cam) or (van nam)) xuc va tinh bai cua te*".
