Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
trinh vet » trinh viet, trinh vat, trinh ven
ho chieu » theo chieu, hoc thieu, doi chieu
trinh ve » trinh he, trinh va, trinh vi
cong van » cong vang, cong san, song van
nhan tai » hang tai, van tai, toan tai
toan tap » toan ban

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: ho chieu xanh - canh ((trinh ve) OR (trinh vet)) nhung cong van ((nhan tai) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh ((trinh ve) or (trinh vet)) nhung cong van ((nhan tai) or (toan tap))*.
