The 132-metre-high city of Kochi-Matsuyama on the top of Shengshan Mountain belongs to the same vertical Hirayama City of Japan as Jilu City. In terms of appearance, size, momentum, status, Matsuyama City and Jilu City, there is nothing comparable. Nevertheless, we must not abandon this visit. The 360-degree view after the 132-metre summit is a spectacular sight. Even today's weather conditions are so bad that the Inland Sea of Seto in the distance is almost completely destroyed by fog. However, if the vast plain inlaid sea looms like a sea of clouds and illusions, it may be unique in Japan's famous cities. Second, it has a vast field of vision, as if I have passed through several famous cities without any right, can not be expressed. Moreover, today's vision is far limited by the weather, you can imagine the vast plain inlaid in the boundless blue sky and sea when the air is fresh and clear. What a must-see place for a tour of four countries!
