It depends on where you are ~ If you are in Haidian, I recommend you to go to the Summer Palace Gallery ~ If you are in Chongwen Xuanwu, you can go to the Temple of Heaven ~ There are fan clubs in some old parks in Beijing.

The most important thing is that it is basically free (it is also possible to get an annual ticket for the park! )

Don't be so polite ~ Now there are citizen schools in almost every community in Beijing, which are funded by the government ~ You can contact some friends who want to learn Peking Opera and suggest that the community set up such classes in your citizen school ~ The expenses are funded by the government ~ You don't have to pay ~ They will invite some experts and scholars to train the residents ~ (I am in charge of the citizen school by the municipal party committee) Hehe ~. Besides, I just looked at it for you ~ It seems that the formal training school is Beijing Giant School in Beijing. Please check online ~ Best wishes ~
