Writing papers on behalf of others is academic misconduct and illegal. Writing a paper on behalf of others refers to letting others finish the paper on their behalf, which not only involves academic ethics, but also violates the law. According to the provisions of Article 144 of the Criminal Law of People's Republic of China (PRC), "it is a crime of cheating to substitute examination papers by cheating, bribery and other improper means, and it is also a crime of cheating to substitute examination papers by prostitution, gambling, drug abuse, smuggling and drug trafficking." Writing papers on behalf of others will not only affect their academic achievements, but also bring legal consequences. Everyone should establish a correct academic concept, strive to improve their academic ability, and finish their papers honestly and diligently.
