Mood wall lets commuters tap feelings in Changsha

There is also a punching wall, which is wrapped in foam, similar to a punching bag. It comes with a screen displaying a strength index – the higher the number, the harder the punch.

The installation has gained popularity online. Netizens said they have been "cured" by it, while others said they could not help but hit the emotion buttons and feel much happier afterward.

The staff explained that the stress-relief wall component functions like a punching bag. They clarified that a recent malfunction in the strength index screen was due to a technical flaw in the design. The screen is under maintenance. However, the plush toys and mood buttons remain fully operational for public use. Staff noted that Yingbin Road Station, being a transfer with high passenger volume, naturally sees more people interacting with the buttons.
