"2 1 1 project" is a higher education construction project initiated by China municipal government in 1995, aiming at improving the higher education level and international competitiveness of China. The project is named after the traditional lucky number "2 1 1" in China, which represents the construction plan of 100 key universities and disciplines in the early 20th century.

The main goal of "2 1 1 Project" is to support a group of universities and disciplines with potential and strength, improve their teaching and research level, cultivate high-quality talents, and promote the modernization and internationalization of higher education in China.

"2 1 1 project" covers some well-known comprehensive, science, engineering and normal universities in China, and has made outstanding achievements in teaching, scientific research and personnel training. In China's higher education system, universities listed as "2 1 1 project" are usually considered as high-level universities.

It should be noted that although "2 1 1 project" has played a positive role in promoting the development of higher education in China, it does not mean that other universities that are not included in "2 1 1 project" are not good, nor does it mean that all universities are included in "21/kloc-" Therefore, when choosing a university, many factors should be considered comprehensively, including teaching quality, specialty setting, teaching staff, subject development, etc., not just whether it is included in "2 1 1 project".
