2020 is the year of the completion of a well-off society in an all-round way and the "13th Five-Year Plan". The situation facing the petroleum and chemical industries is more complicated, challenges still exist, and the entire industry faces a lot of work. We must continue to tell the chemical story. The key is to stick to one main melody and sing five movements. The main theme is to make stability the top priority of the entire industry to prevent economic ups and downs. It is also necessary to sing the new era of "innovative development, structural transformation and upgrading, green development, "Belt and Road", and efficiency improvement". I hope that the chemical industry story in 2020 will be more exciting and deeper than 2019
