Perhaps you should try some spelling variations:

hanh vai » hanh vi, hanh va, hanh tai
hieu van » hieu va, thien van, lieu va
sua chu » sua chua, cua chu, bua chu
van cam » van nam, van lam, van cau
cam duc » cam xuc, cao duc, pham duc
sai ky » sac ky
tu sai » tu bai, tu san, tu cai
o hoi » co hoi, o hoc, o hai
x hoi » xa hoi, x ho, 5 hoi

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 ((x hoi) OR (o hoi)). hieu van cam duc va ((hanh vai) or (thanh hai)) sua chu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky nang ((x hoi) OR (o hoi)). hieu van cam duc va ((hanh vai) OR (thanh hai)) sua chu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky nang ((x hoi) OR (o hoi)). hieu van cam duc va ((hanh vai) or (thanh hai)) sua chu*".
