【推荐1】Spring Festival is a special occasion for children also because they receive red envelopes (hongbao) from elders on the occasion. While in the past, children used to rejoice after receiving hongbao from elders in person, nowadays they mostly receive them online thanks to the coming of mobile payment apps such as Alipay and WeChat, which urged the central bank to create a new legal tender (法定货币) for online transactions (交易).

That’s how the digital renminbi came into being. The digital currency has increased the types of negotiable instruments issued by the central bank and diversified the payment tools. Yet the promotion and application of the digital renminbi faces some challenges, especially because it is yet to be recognized nationwide.

First, thanks to Alipay and WeChat, they account for almost 95 percent of the mobile payment market. Based on these payment apps, a complete consumer application ecosystem has been established covering activities such as shopping, traveling, giving red envelopes, making payments, and investing funds. In the short term, however, the “digital renminbi wallet” can hardly shake the existing payment and transaction ecosystem.

Second, payments made through the digital renminbi are not channeled through bank accounts. Instead, they are deposited directly into “digital accounts” and transactions can be completed through an electronic device, which may cause users to worry about the security of their deposits, particularly because if a user loses his or her cell phone, he/she could lose a lot of money.

Third, the digital renminbi may be a substitute for cash, but the public is not attracted to it because it has no appreciation value. While people can earn interest on bank deposits, no interest is offered on digital renminbi deposits.

In fact, the original design of the digital renminbi was for retail —to make transactions more convenient for consumers and merchants. The central bank, too, has said all the research and development is to ensure the digital currency replaces cash, which shows its aim is to use it for retail, especially to make life more convenient for the public with the help of the Internet and mobile apps.

In 2016, Lorna challenged her 12-year-old son Sivert to stay off social media until he was 18. If he completed the challenge, she’d award him the cash on his eighteenth birthday.     2    

Sivert said it wasn’t too difficult to live without social media, and he didn’t think about it much during the six years.     3     The only app he once used was Snapchat, which he deleted a day after trying it out.

Now $1,800 richer, Sivert told CNN he hasn’t thought about what to buy, but it’ll likely be used for his study at the University of Northwestern St. Paul, which he’ll attend in the fall But he has already decided on his first use of social media: getting Instagram.

After Sivert’s success, Lorna shared the challenge online. She said it was some of the best money she ever spent. Other parents have seemed interested in trying it out too. “    4     But the question is to use it in a healthy way,” Lorna noted. She added she thinks her son now has a “different perspective” on social media than he would have at age 12.

Sivert is the youngest of four children.     5     When one of her daughters was 16, Lorna took away her phone. Lorna says her daughter later thanked her for doing so, as it improved her mood.

“For some reason, kids and adults feel so comfortable behind a screen,”. Lorna mentioned the kinds of comments people post. “I’m so happy Sivert didn’t have to read any of that.”

【推荐3】Some people browse TikTok and Instagram for recipes, memes and colorful opinions on the news. Erin Coleman says her 14-year-old daughter uses these apps to search for videos about mental health diagnoses (诊断).

Over time, the teen started to self-identify with the creators, according to her mother, and became convinced she had the same diagnoses, including depression, autism (自闭症), mysophobia (洁癖) and agoraphobia (a fear of leaving the house).

“Every week, she would come up with another diagnosis,” Coleman told CNN. “If she sees a hint (暗示) of herself in someone, she thinks she has it, too.” After undergoing testing for mental health and medical conditions, her daughter was diagnosed not with the long list of conditions she had thought about but with severe anxiety. “Even now, she doesn’t always think the specialists are correct,” Coleman said.

Social media platforms, including TikTok and Instagram, have come under mounting scrutiny (审查) in recent years for their potential to lead younger users to harmful content and worsen what experts have called a national mental health crisis among teens. But Coleman is one of nearly two dozen parents who told CNN that they are worried about a different but related issue: teens using social media to diagnose themselves with mental health conditions.

A growing number of teens are turning to social platforms such as Instagram and TikTok for guidance, resources and support for their mental health, and to find conditions they think match their own—a trend that has alarmed parents, doctors and school counselors (辅导员), according to interviews with CNN. Some teens start to follow creators who discuss their own mental health conditions, symptoms and treatments; others have come across posts with symptoms checklists to help decide if they meet the criteria for a diagnosis.

Using the Internet to self-diagnose is not new, as anyone who has used WebMD knows. And there can be some benefits. Some parents said social media has helped their teens get mental health information they’ve needed and has helped them feel less alone.
