In our designgroup of this product, several of our good friends have set up a small group of six people. When I first came to Germany, German was not good and I had few friends. Thanks to Phil, he took the initiative to chat with me and took me out to participate in the event. It is also that he pulled me into this small group. Everyone here is very different in style. There are from Germany, China, South Korea, and the Middle East. There are also atheists, Christians, and Buddhists. But we all good. Compared to the entire class, we communicate more and be more efficient in this small group. Btw. I turned out to be the oldest inside.
