In the heart of the bustling metropolis of Shanghai, where neon lights intertwine with the stars above, there lived a man named Li. Dressing in a simple blue shirt, Li led a mundane life of serving tea at a quaint café. Yet, his eyes held a glint of curiosity and longing.

One tranquil evening, as Li closed the café, he felt an inexplicable pull towards the nearby Hongkong Temple Park. In the stunning, colorful image of the Chinese boy underwater that danced on his mind, Li saw a parallel world hidden beneath the tranquil lake. He felt drawn to it, perhaps seeking an escape from his monotonous life.

With the full moon as his guide, Li ventured into the park. He took off his blue shirt, revealing his lean, tan body grown accustomed to delivering steaming teas, and dove into the lake. Instantly, he was enveloped by vibrant, mystical underwater waters teeming with life. He discovered a hidden, breathtaking underwater world, a realm where time stood still, and life flourished. Surrounded by these vibrant, exotic creatures, Li found a sense of freedom and fulfillment he had never known before. Within moments, the man in the blue shirt became one with this breathtaking underwater world.
