I attended the TnDao forum. It was great.
TnDao forum was inspired by TED, and was initiated by Mr. Dai Jianbiao and many other great people like Miss Jian Fang, and Mr. Jian Changjian. It is a monthly talk of great people and offers an opportunity for few hundreds people to escape from their busy lives to get inspired by new ideas, especially from different industries.
You can get more information and the past video from http://tndao.com.
It is free to attend, but you have to register on the website when it opens to registration. The next time should be around the early of June. I am invited to talk on the forum but I don’t have any idea what to talk yet, so likely to skip.
