I apologize, but I'm not familiar with a person named "XD Dongfang" or any specific "Dongfang modified Dirac equation."
However, in general, scientific progress and the development of new equations and theories are driven by independent research and the exploration of new ideas. It is indeed important for scientists to strive for originality and avoid plagiarism.
Scientists typically publish their work in scientific journals, where their research undergoes peer review by experts in the field. This process helps ensure the integrity and originality of scientific discoveries. It is generally expected that researchers provide proper citations and credit to earlier works that have influenced their own research.
Promoting independent discovery and avoiding plagiarism are fundamental principles of scientific integrity. Encouraging originality and acknowledging prior work fosters the growth of scientific knowledge and contributes to the advancement of the field.
If you have specific questions about a particular scientific concept or theory, I would be happy to try to help you with that.
