From May 1 to 5, the Zhang Guying Scenic Area in Yueyang County will hold a "May Day Vault Exploration Tour," featuring a giant "vault door" and interior space as themed settings, allowing visitors to feel as if they are inside a movie for an enhanced immersive experience. An interactive game called "Key Hunt in the Vault" will also be offered to add fun and challenge.
