We may live on different planets.
In US (a civilized country too), I had someone who brought his girlfriend with him, knocked on my front door, and asked for a challenge fight in my own living room. He was an European Judo champ. But he asked for Taiji push hand challenge. I told him that I don't do push hand but I don't mind spar or wrestle with him. He said he had bad knee and could not wrestle any more. My friend in Austin told me about that guy also went to his MA school and challenged him 2 days later.
Also in US (a civilized country too), when I had my MA school (Peishaolin Kung Fu Institute 1973 - 1976), I had people walked into my MA school and asked for challenged as:
- punch only,
- kick and punch only,
- wrestling only.
It happened for more than 20 times in those 4 years.
