In fact, this is what I have been thinking about for a long time. I found a good training class, that is, Zhang's magic eloquence training class. I often collect his teaching videos from the internet, but I think his tuition is a bit expensive, so I didn't go to class. I added his WeChat, listened to his WeChat every day, and then did what he said, which can improve a lot. The most important thing is to defeat yourself first and dare to speak!
