Be sure that the school teaches the three great pillars of Shao-lin, if not you are wasting your time. Be sure the teacher has a family tree showing his past teachers and is willing to tell you who they are. Be sure money is not the motivating factor for the teacher. Of course, finances are needed to run a school, but it should not be an excessive amount. Check to see that the teacher's past is what he or she claims it to be.
Many teachers have little connection to what they claim.
If they are true teachers their past should be no secret. If you hear negative reports concerning a teacher, there might be some truth to it. It should be investigated. The school should be well equipped and run in a orderly manner. Notice the teachers attitude.
