Perhaps you should try some spelling variations:
phieu lang » hieu lang, chieu sang, nhieu tang
hanh trang » thanh trung, hanh trinh, minh trang
nhung cong » dung cong, thong cong, hang cong
hoi phieu » hoi hieu, co phieu, doi chieu
cua nhung » va nhung
cong dan » cong san, cong tan, huong dan
chan tap » han tap, phan tap, toan tap
chan ta » chan tha, nhan tai, nhan tao

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: hoi phieu lang - ((hanh trang) OR (canh tranh)) cua nhung cong dan ((chan tap) OR (chan ta))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoi phieu lang - ((hanh trang) or (canh tranh)) cua nhung cong dan ((chan tap) OR (chan ta))~".
• Adding a wildcard symbol may retrieve word variants: hoi phieu lang - ((hanh trang) or (canh tranh)) cua nhung cong dan ((chan tap) OR (chan ta))*.
