Not reliable. Yan Yafei Investment Management Co., Ltd. is unreliable and a scam. "Yan Yazhen APP" is not formal. It releases color advertisements through web pages, social software, text messages and other forms to trick people into clicking on links to download apps, and then arranges "beauty customer service" to complete tasks with "placing orders or betting" as bait, carry out special services, and implement telecommunication network fraud. I would like to remind the general public to be vigilant and not to believe in such situations.
