Does Zhu Yanze's emotional password course really refund tuition fees?

Tuition refund, but also deduct a certain fee.

The teacher spoke very systematically, making some complicated problems easy to understand, and the whole process was full of dry goods. The course content is highly theoretical, combined with the teacher's years of work experience, very practical and worth having!

Dr. Zhu Yanze is a man of great learning. His course is not mysterious, but it has profound tranquility and warm humor. Although he doesn't look like anyone's mentor or an innovator of the new era curriculum, he can easily play both.
