Perhaps you should try some spelling variations:
trinh cua » trinh luat, trinh quan, trinh luan
cong vang » cong lang, cong quang, cong ngang
chi hanh » chi nhanh, chi thanh, thi hanh
tinh cua » sinh cua, tinh chat, tranh cua
song van » hoang van, trong van, duong van
doi chi » doi khi
tuan cu » tuan tu, quan cua, tuan thu

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: doi chi hanh - hanh ((trinh cua) OR (tinh cua)) nhung ((cong vang) OR (song van)) tuan cu~.
• Adding a wildcard symbol may retrieve word variants: doi chi hanh - hanh ((trinh cua) or (tinh cua)) nhung ((cong vang) or (song van)) tuan cu*.
