Residents exercise at an outdoor smart gym in Shenzhen Central Park in Futian District yesterday. The gym is free to use, and people can scan QR codes on the gym’s facilities to generate their physical test reports and record their own exercise data. The gym’s facilities were quite popular during the seven-day Spring Festival holiday, the municipal urban management authority said. Shenzhen’s public parks are getting smarter in recent years as smart applications and facilities have been set up to provide residents with a wide range of convenient services. Sun Yuchen
