A Suggestion for Immigration Officers
I heard that there are many "fake" Falun Gong practitioners trying to seek asylum in the US or other countries. This makes things more difficult for the immigration officers to decide who are genuine and who are fake. Sometimes they get things wrong.
If I were an immigration officer, I would ask the applicants to sit with "double lotus" positions and see if they can do it, and for how long. From what I can see, the majority of genuine Falun Gong practitioners, especially veteran ones, can do this very easily for at least 30-60 minutes.
Don't believe it? You can cross your legs and see if you can!
