Perhaps you should try some spelling variations:
trinh quan » tinh quang, trinh luat, trinh han
nhung cong » dung cong, thong cong, hang cong
trinh cua » tinh cua, trinh luat, trinh luan
chi hanh » chi nhanh, chi thanh, thi hanh
cong van » cong vang, cong san, song van
doi chi » doi khi
tuan cu » quan cua, tuan thu, than cua
tuan tu » tuan thu, tran tu, toan tu

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 (trinh quan)) nhung cong van ((tuan cu) OR (tuan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi hanh - hanh ((trinh cua) OR (trinh quan)) nhung cong van ((tuan cu) or (tuan tu))~".
• Adding a wildcard symbol may retrieve word variants: doi chi hanh - hanh ((trinh cua) OR (trinh quan)) nhung cong van ((tuan cu) or (tuan tu))*.
