'''Magic circles''' were invented by the [[Song Dynasty]] (960&ndash;1279) [[China|Chinese]] mathematician [[Yang Hui]] (c. 1238&ndash;1298). It is the arrangement of natural numbers on circles where the sum of the numbers on each circle and the sum of numbers on diameter are identical. One of his magic circles was constructed from 33 natural numbers from 1 to 33  arranged on four concentric  circles, with 9 at the center.  
==Yang Hui magic  circles==
Yang Hui's magic circle series was published in his ''Xugu Zhaiqi Suanfa''《續古摘奇算法》 (Sequel to Excerpts of Mathematical Wonders) of 1275. His magic circle series includes:  magic 5 circles in square, 6 circles in ring, magic eight circle in square
magic concentric circles, magic 9 circles in square.

Yang Hui's magic concentric circle has the following properties

*The sum of all numbers on each circle (not including 9) = 2&nbsp;&times;&nbsp;69
*There exist 8 semicircles, where the sum of numbers = magic number 69; there are 16 line segments(semi circles and radii) with magic number 69, more than a 6 order magic square with only 12 magic numbers.
