Forty-two years, almost two generations of the years of rotation. 240,000 live life instantly disappeared. Forty years, the earth's earth-shaking changes in China can not erase this painful memory. The museum is built to remember the lost life, the mourning of the survivors, and more importantly, to appreciate the easy death of life so as to cherish it, carry the depth of suffering and thus dig the glory of human nature. The museum is built underground, on the ground is the ruins park, and some earthquake relics are left.
