As the Congress chair of ICME-14, I cordially invite you to participate in the Congress to be held in Shanghai from July 12th to 19th, 2020.

As an ancient country with a 5,000-year history of civilization, China boasts a brilliant tradition of mathematics and mathematics education. In recent 100 years, the introduction of western mathematics and mathematics education and their integration with traditional Chinese culture and education have fostered new achievements in mathematics education of modern China. Shanghai, a well-known metropolis in the Far East, is a powerful engine for the economic and social development of China and a window of China's opening-up policy. In addition, it is also the cradle of modern Chinese mathematics and mathematics education and the birthplace of the Chinese Mathematical Society. East China Normal University is one of the top universities in China and takes the lead in the development of teacher education in China. The mathematics education team of ECNU has a great influence both at home and abroad. Taking consideration of all these facts, I believe that the ICME-14 hosted in Shanghai will be a grand academic Congress and a great surprise for the colleagues around the world.

I am very much looking forward to seeing you at ICME-14 in Shanghai. I am sure your participation will contribute greatly to the success of the ICME-14.
