Dear Master Chen,

That was great! I’ll be smiling all day. Perhaps you’ll get the Palme d’Or at Cannes next year!

If you haven’t seen this video, you’re missing out on some excellent information. Both of the concave circle videos part one and two are an excellent addition to the wealth of knowledge Chen Zhonghua has released. I’m still rather amazed by the level of knowledge possessed by Chen Zhonghua combined with his ability to teach. As you watch the video, as happens so many times when discussing opposite concepts, some of the usage of the terms concave and convex are inadvertently reversed. But if you think about it carefully, you can easily realize which circle is being discussed. Excellent series of videos on concave versus convex circles….thanks again Chen Zhonghua!!!

Hi Admin, any additional information about the video Concave Circle 2 as the trailer is in fact the content of the part 1 video which I already bought. Appreciate any description and information about the length of this video. Thanks.
