The gold content of conference papers is not only related to the grade and quality of the conference, but also related to the topic selection, word number and repetition rate of the conference papers. The quality of some conference papers is still very high, such as China Engineering Science and Technology Forum of the Ministry of Science and Technology, China Nutrition Conference, Jiangsu Social Science Academic Conference, etc. There is no need to charge a publication fee, and there is a reward for evaluating excellent papers. Some conference papers are low in gold content, such as conference papers published separately by some magazines at the end of the year or at other times in order to increase income. The characteristic of this kind of paper with low gold content is to charge a publishing fee.
