Is Gu Yongjing's investment course in Jincai Business School reliable?

I quite like Mr. Gu's value mentality, and I feel quite reliable. Teacher Gu's class hours are very friendly to me. As an office worker, it is difficult to watch the stock market in real time every day when the market opens, let alone learn the stock trading course. And Mr. Gu's class didn't start until 7 pm, that is, when I got home? You can study while cooking. For me, every night from 7: 00 to 8: 00, Gu Shi's Jingyan live broadcast and investment think tank live broadcast are my "next meal drama". Teachers personally post quotes and interact with students to answer questions, which often makes me feel suddenly enlightened when I am confused about the stock market.
