I went on a day trip to Chongqing Ordovician Park, an amusement Park located on top of Heishan mountain, two hours car ride from Chongqing
At the entrance you can get a map of the park. It has a QR Code on it, by scanning it you can check the waiting lines for the different atracctions. I went in March, but in the summer its probably gonna be crowded, so it will be helpful to know where to calculate how much time for standing in line.
