What's up with the Tsinghua professor who argued for the expelled homeless singer?

I've seen this video, and the professor, true to form, makes a convincing argument.

What happened

In the Hangzhou Drum Tower scenic area, a homeless singer was singing and performing, but was expelled by the scenic security guards. The main point is that the scene here is not allowed to set up stalls singing chanting. An old professor, who was a spectator, came up to help the singer and the security guards.

The old man said: Hangzhou is not to create a national model city ah, if they bring a negative impact, then we have no problem immediately banned, in fact, I also happen to want to rest here, they happen to sing here, this is not a very good thing for me ah? Then I gave him the change in my pocket, and he made a little money, and I took a break, right?

Onlookers showed solidarity with the old man and agreed with him.

It was reported that the place where the wandering singer was performing was originally occupied by a group of elderly people who were dancing in the square, so the singer did not sing for a while before he was reported.

The video was put on the social platform, a time was a lot of forwarding, comments clear appreciation of the elderly. At the same time, the relevant management of the Drum Tower scenic area also contacted the video of the wandering singers, for them to designate a special performance venue.

But this matter also let a lot of people do not understand, why the same place, dancing can be square dance, singing can not? The homeless singers in the video also only have a piano, no stereo and other large decibel equipment, I'm afraid that does not see more noise than square dance.

And is there a placeholder for this sort of thing?

Compared with the Tsinghua professor, those who reported the square dancers, the broad-mindedness is also too small, the old professor and the elderly there is still a gap.

A modern and civilized city, tolerance is a very important temperament. Inclusion is the only way to have diversity, and if the city is full of square dancing, what beauty is there?

And, the management of a scenic spot, the tolerance of wandering singers, to some extent, also shows the government's care for the disadvantaged. A large city, can not tolerate one or two vagrant singers, such a city construction of the more modern, the more lack of human feelings.
