Today, I received a phone call from an institution in Chen Anzhi, inviting me to attend a lecture by a lecturer named Zhang Manqiang. Who has listened to this lecturer's class? Give a suggestion.

I am a case. I used to do traditional business and sell rice. Before attending Zhang Manqiang's course, I earned 30,000 yuan a year, and after completing the course, I earned 300,000 yuan a year. Zhang Manqiang's course is really good and worth listening to. He helped many people realize their dreams in less than a year. The more I know him, the more I think he is powerful! I really really admire him!
