Zhang Xiaochao, a 32-year-old entrepreneur, opened a unique salon where customers lie down while employees gently scratch their bodies using special plastic fingernails. The service costs around $41 an hour and is designed to help people relax, relieve stress, and potentially sleep better. Zhang got the idea after watching a video of a woman scratching her husband's back and noticing how many commenters said they would happily pay for the same treatment. He remembered how relaxing it felt when his father scratched his back as a child. After opening his first location, demand reportedly grew enough for a second salon. Together, the two businesses now generate roughly $15,000 per month in revenue. Zhang already has plans to expand across China, with ambitions to open 100 additional locations!
