I think this method is very good and can effectively prevent the spread of the epidemic. This is also a form worth promoting for the safety of people's lives.

First of all, we all know that the epidemic abroad is still very severe. In many foreign countries, tens of thousands of people are still infected with the virus every day. It has been nearly a year, but it is still not well controlled. Therefore, when holding concerts at this time, activities that will gather a large number of people, we must take the epidemic into consideration. If you are not careful, a large-scale epidemic will occur. Infection will cause panic and threaten everyone's life.

Secondly, the concert in Vienna can be called the most solemn concert in the world, but as music fans we all know that the concert will not be held if there are no people to participate. It's very lively, so if you have decided to hold it online, then cloud applause is also a kind of encouragement to the performers, and it can also create an atmosphere very well, and this atmosphere is what the concert needs. , what the concert wants to express is the audience's passion and everyone's love for music, so that everyone will have an immersive feeling.

Finally, I think this method of cloud applause is worth promoting, just like we do in school. College students have not been able to start school before because there was no good control before. Many people take online classes at home. During online classes, there are also forms of cloud applause and cloud answering, which can effectively answer the teacher's questions, and can also provide encouragement and responsibility to the teacher. In this way, the classroom atmosphere will be very good. Therefore, I think this form is suitable for many activities carried out online. It is very beneficial to people's life safety and will have a good impact on society and the world.
