Personal WeChat can't build a love fund group to receive red envelopes, because it is a public welfare activity of China Love Fund Group, and it must be audited and supervised by the government or the public, and it must be enterprise certification or government certification. In Xiangcheng, China, there is a WeChat group of more than 300 people founded by a company. At the time of its establishment, the friends in the group didn't know each other, and they were usually busy. They contacted by WeChat and "made red envelopes" every day through goodwill. Therefore, personal WeChat cannot build a love fund group to receive red envelopes.
