Xue Rui didn't hang any signs, just posted a QR code for downloading the app in front of the Xigua stand.
Attracting a crowd wasn't a problem at all. In a place swarming with new students, there was no need to hang a banner; the fresh, juicy Xiguas sitting there were a living advertisement.
Students had been baking under the hot sun, so getting even a sip of water was a luxury, let alone finding a Xigua stand set up in a corner, its canopy provided by the school.
"How much are the Xiguas?" a student in a military training uniform asked.
"We don't sell Xiguas." Xue Rui waved his hand, pointing to the QR code in front of him. "Hey, miss, just download the app, register an account, and post a selfie. I'll give you a Xigua for it."
The female student looked at Xue Rui doubtfully. "A whole Xigua isn't cheap. All I have to do is post a photo?"
Xue Rui nodded seriously. "Absolutely. No catch. It's just like posting a status on QQ—a caption with a photo is all you need."
