Fame Spreading Far and Wide
Any great teacher that became a secondary saint would give a week worth of public lectures.
By doing so, they could firstly expand their influence and promote their learning and expertise. After all, great teachers relied on their learning and achievements to leave their mark for generations to come.
Secondly, it was to return their debt to the great teacher world, sharing their experiences with the other great teachers.
Great teachers who could reach this stage definitely wouldn't be selfish and hoard their knowledge. Basically, they were willing to teach everything they had ever learned.
Zhang Chun was a grateful individual. During the lectures he gave in these ten days, he didn't stint on his praise of Sun Mo. During every lecture, he would say that if it wasn't for Sun Mo acting in time, he would have been dead.
Hence, Sun Mo's fame grew even greater.
