I also watched the video "Front Wave" released by the United States. The video "Front Waves" shows pictures of people riding horses, climbing mountains, skydiving, fitness and Cosplay, which has been deeply impressed so far. So in order to find out whether the middle-aged and old-aged life shown in Qian Lang really exists, I specially downloaded the American text and found that there are many such middle-aged and old-aged lives in the American text. They make friends and share their life or hobbies through interest, which seems to have discovered a new continent, which is completely different from the middle-aged and elderly people I imagined, and has solved my misunderstanding of this group for many years.
