In southern China, in a newly built neighborhood, a security guard is taking a nap. He helps pick up a package and takes the chance to sneak into his friend’s place. He wanders around inside until he got caught. He learned about the news of the relocation and recalld his memories of the treasure he had buried in the ground in his childhood. The sound of building construction is going on and on till the buildings eventually built up. Digging up memories seems pointless.
