On November 18th, Xiaoyu, a female undergraduate lost her smartphone due to the trick by her Wechat friend when she went for a dinner with him. Now, the police have started to investigate the case.

　　At 11 o’clock of November 18th, Xiaoyu answered a call from her Wechat friend Xiaogang for his invitation of a dinner in a hotpot restaurant.  After they met there, Xiaogang led Xiaoyu to the reserved table and asked the waiter to serve food.  After a while, Xiaogang said that his telephone was dead and wanted to borrow her phone to call another friend. Xiaoyu gave it to Xiaogang without hesitation. To her surprise, Xiaogang and his friend did not turn up since then. Xiaoyu borrowed a waiter’s phone to dial her own phone, but her phone couldn’t be reached. When the police arrived, Xiaoyu knew nothing about Xiaogang except his Wechat number. （Reporter Gong Changjun; Correspondent Tong Li）
