How much is the ticket? Is there a guide?

I went there on November 1st, the entrance fee was 30 yuan, the parking fee was 5 yuan, and it was free to buy incense and ring the bell. I paid 1 yuan for one knock, and usually knocked 3, 6 or 9 times. There is a commentator, and there should be a fee (there is a QR code card hanging around the neck)!
