I had the great honour of meeting him several times at the main school in Beijing. Despite being retired he would come in to observe some classes. Inevitably his love and enthusiasm for the art would end up with him offering advice and instruction to those fortunate enough to be present.
He was a wonderful human being and will be greatly missed by his family, friends, disciples, students and all those who met him.
