2. As far as SCI papers are concerned, most researchers in China face the defect of insufficient English ability, especially for older and professional scientists, the content is not a problem, and English often becomes a bottleneck. SCI papers are still mysterious to most domestic scientific and technological workers, and it is difficult to publish them. Based on this, it is unfair for most scientific research institutions, universities and other units to introduce it as an evaluation standard. Although there is no evaluation standard of human intervention, researchers have to waste their energy on writing and publishing SCI papers while working, although this makes China's scientific research in line with international standards. Cultivating the habit of China scientific and technological workers to use SCI official website to search existing papers and scientific and technological achievements has restricted the level of science and technology in China, forcing researchers to devote part of their energy to foreign languages, making a large number of excellent research achievements flow into English journals, undermining the development of Chinese journals and reducing the "liquidity" of Chinese in the field of science and technology.
