What happened and Why?


 I did not take into account that physical contact between the Chinese is not accepted, especially in public. I had embarrassed the instructors by hugging them and placed them in an awkward position. Touching the instructors was very inappropriate.  Although in the U.S. hugs are generally welcomed, in China they are definitely not.  Physical contact is kept at a minimum, especially between foreigners and older Chinese citizens, particularly teachers. I wish I had been a little more careful and observed more before I acted spontaneously.
