Zhao Lulu, a sophomore majoring in international economics and trade at the university, is one of the part-time couriers. "I often work here on Monday and Tuesday mornings, and weekends when possible. I can earn about 40-50 yuan per day,  enough for my daily expenses," Zhao said.

The app has quickly gained popularity among students at the university. "This app saves time and money for postgraduate candidates like me," Mao Jiaju, a junior student, told Chinanews.com on Monday. "The quality and safety of food available on the app is more reliable than outside delivery platforms, but the delivery service is just as convenient," he said.
