Mr. Huang, who lives in Puxie City in the urban area, is 20 years old this year. On the afternoon of October 1, two "monks" came to "make a connection", and he donated RMB 100,000 for this purpose. Later, when his family learned about this, they thought that Mr. Huang might have been deceived. Accompanied by his family, Mr. Huang went to the Puxie City Police Station of the Lucheng Public Security Bureau to call the police. At the same time, the institute's road patrol team happened to encounter these two "monks" while patrolling the streets. After asking, the two were hesitant to speak. One of the older "monks" quietly handed over a donation book. Ben tore off a page, took a sip of mineral water, spit on the paper, and threw it in the trash can. This move immediately aroused the suspicion of the team members. After the team members picked up the page and opened it, they found that there were many names and addresses written on it. The two were immediately taken to the police station for further investigation.
