I began to participate in the activities of the WAAMA 20 years ago, and I have been engaged in abacus for 40 or 50 years. I would like to thank President Liu, Secretary-General Cheng and all of you for their contributions to the development of abacus and mental arithmetic and international friendship. Before, we hoped to hold a conference in South Korea. Three years ago, the plan was very detailed. But because the epidemic situation was not implemented, I am sorry. I don't know when it will be held in South Korea. In international relations, China has encouraged the popularization of abacus and mental arithmetic at the national level. I am encouraged by this, so I hope to hold conferences and competitions in South Korea. Also, in the past three years, international relations have been tense, oil prices have been high, and the prevalence rate has been high. We have faced a series of difficulties. We have not been able to invite you to Korea, and we cannot see when the competition will be held in the future. I feel pity for this. Abacus and mental arithmetic not only promotes brain development, but also promotes human communication and friendship. The WAAMA is a useful exchange platform for the international abacus community. I admire the efforts of Chinese and WAAMA member units. I hope the epidemic will end soon so that everyone can get together. Although there are many difficulties in the development of our career, we did not stop. In order to further promote friendly exchanges and deepen friendship, I hope you will continue to promote the cause of abacus with full enthusiasm in the future. We hope that the international situation will be stable and peaceful so that your efforts can achieve greater success in the future. Focusing on China, Japan and South Korea, Taiwan, China, Southeast Asia, etc. in Asia, we hope to continue to expand the sphere of influence of the abacus cause in the future and enhance the international influence of the WAAMA. It is believed that the epidemic will not last forever and will end one day. Moreover, the communication is also very developed now. Even if it cannot be face-to-face, it can also be communicated online like today. As a leading country, China has led the development of the abacus cause. It has also played a leading role in many other social and political fields, made many contributions to the international community, and made positive contributions to world peace and the development of human basic education. It is believed that China will make greater contributions in the future, and we also look forward to such contributions. At the same time, we also know that China has made a lot of contributions and sacrifices, and pay tribute to you. It is believed that China will lead the development of abacus and mental arithmetic, and the future is bright. Once again, I would like to express my apologies and thanks. I believe we will make greater achievements in the future. I also hope you can work hard together to help each other and develop together. I hope that one day there will be an abacus conference in South Korea. Let's work together hand in hand.
