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

			== Research ==
			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 = 23 + 7·11.

			== Commemorations ==
			[[File:A statue of Chen Jingrun.JPG\|right\|thumb\|Chen's statue in [[Xiamen University]], China.\|250px]]
			The [[Asteroid]] [[7681 Chenjingrun]] was named after him.

			In 1999, China issued an 80-cent postage stamp, titled ''The Best Result of Goldbach Conjecture,'' with a silhouette of Chen and the inequality:

			: <math>P_x(1, 2) \ge \frac{0.67xC_x}{(\log x)^2}.</math>

			Several statues in China have been built in memory of Chen. At Xiamen University, the names of Chen and four other mathematicians — [[Peter Gustav Lejeune Dirichlet]], [[Matti Jutila]], [[Yuri Linnik]], and [[Pan Chengdong]] — are inscribed in the marble slab behind Chen's statue (see image).
