Walk to Toyoshima Art Museum, get a reservation ticket for a visit after two hours, and set off for the Christian Poltanski Heartbeat Museum. "Death is not the end of life, forgetting is. The heartbeats that prove to be alive should be recorded, stored, amplified, and listened to by loved ones," he said. He has collected 120,000 heartbeats and stored them on Seto Inei Toyoshima, Japan. The dark hall is accompanied by a flashing heartbeat. The intensity of the light is the same as the intensity of the heartbeat, and the weak heartbeat can only make the light bulb faint, and the strong heartbeat can make the light bulb illuminate the mirrors around it.
