Today is the 15th anniversary of the Wenchuan earthquake. Liu Daobin, who was working at a telecommunications company, braved aftershocks to rush into the house, grabbed the only local maritime satellite phone, and sent the first distress signal to the outside world.

The pain caused by the earthquake has gradually been healed by the years, and the moment of "May 2008, 5 12:14:28" is still remembered. Some of the people who experienced the earthquake are slowly growing up, some are slowly aging.
