Relaxing your muscle

It was lunchtime. People were gathered in the canteen, eating and chatting.

"Have you heard that the new coach is paired up with Aiguo Jiang!"

"Ew. Jiang is old and bad-tempered, he thinks he is superior to everyone else. Jiang must treat this new coach in the same way. Poor Li is going to have a hard time here!"

"I heard that Jiang had made some nice achievements. He was a national champion, wasn’t he?" someone asked.

"That was ten years ago. Who would remember that!"

"I heard that the leaders are dissatisfied with Jiang’s current status. They say that he is not capable of being an athlete any longer, and are planning to force him to retire. Is that true?"
