Liyuan disciples often burst into tears. The thieves are all looking at him with their swords exposed. Musician Lei Haiqing was so filled with grief and anger that he threw his instrument on the ground and cried to the west. Lushan was angry, tied him in front of the horse trial hall, and dismembered him.
