Editing Chen Jingrun (section)

==Life and career==
Chen was the third son in a large family from [[Fuzhou]], [[Fujian]], China.  His father was a postal worker. Chen Jingrun graduated from the Mathematics Department of [[Xiamen University]] in 1953. His advisor at the [[Chinese Academy of Sciences]] was [[Hua Luogeng]].

His work on the [[twin prime conjecture]], [[Waring's problem]], [[Goldbach's conjecture]] and [[Legendre's conjecture]] led to progress in [[analytic number theory]]. In a 1966 paper he [[mathematical proof|proved]] what is now called [[Chen's theorem]]: every [[sufficiently large]] even number can be written as the sum of a prime and a [[semiprime]] (the product of two primes) – e.g., 100&nbsp;=&nbsp;23&nbsp;+&nbsp;7·11.<ref name="Song2014">{{cite book|last=Song|first=Yuwu|title=Biographical Dictionary of the People's Republic of China|url=https://books.google.com/books?id=DGbyzKLVh30C&pg=PA35|year=2014|publisher=McFarland|isbn=978-1-4766-0298-1|page=35}}</ref> Despite being persecuted during the [[Cultural Revolution]], he expanded his proof in the 1970s.<ref>{{Cite web|url=http://www.chinawriter.com.cn/n1/2017/1218/c405173-29711930.html|title=徐迟报告文学的突破、经验及警示意义|author=Shi Xingze 石兴泽|date=18 December 2017|publisher=China Writers' Association|language=zh|url-status=live|archive-url=https://web.archive.org/web/20191026035456/http://www.chinawriter.com.cn/n1/2017/1218/c405173-29711930.html |archive-date=26 October 2019 |access-date=4 October 2019}}</ref>

After the end of the Cultural Revolution, [[Xu Chi]] wrote a biography of Chen entitled ''Goldbach's Conjecture'' ({{lang|zh|哥德巴赫猜想}}). First published in ''[[People's Literature]]'' in January 1978, it was reprinted on the ''[[People's Daily]]'' a month later and became a national sensation. Chen became a household name in China and received a sackful of love letters from all over the country within two months.<ref>{{Cite web|url=http://mjlsh.usc.cuhk.edu.hk/Book.aspx?cid=4&tid=3821|title=揭开诗人徐迟跳楼之谜|author=Zhang Shouren 张守仁|date=December 2016|publisher=Chinese University of Hong Kong|language=zh|url-status=live|archive-url=https://web.archive.org/web/20201107175338/http://mjlsh.usc.cuhk.edu.hk/Book.aspx?cid=4&tid=3821 |archive-date=7 November 2020 |access-date=4 October 2019}}</ref>
