Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cac luc » cau luc, coc luc, cac nuoc
cuu tre » cua tre, cau tren, cau treo
xanh di » danh di, vanh dai, xanh tai
va xanh » va danh, va hanh, va anh
hieu ve » hieu va, hieu van
luc va » duc va, tuc va, loc va
te cac » tu cac, te cao, de cac
ve cac » va cac, vien cac
o hoi » co hoi, o hoc, o hai

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: te cac ky nang ((5 hoi) OR (o hoi)). hieu ve cac luc va xanh di ((cuu tre) OR (cua triet))~.
• Adding a wildcard symbol may retrieve word variants: te cac ky nang ((5 hoi) or (o hoi)). hieu ve cac luc va xanh di ((cuu tre) or (cua triet))*.
