《宋书·志·卷十三》
扣除一周天，实际位置移动了二百一十八度和度余二万六千三百一二一次与太阳合需二百九十一天和曰余三万八千一百二十六，运行的度数值与此相同。
除一周，定行二百十八度，度余二万六千三百一十二。一合，二百九十一日，日余三万八千一百二十六，行星亦如之。
After subtracting a week, the actual positional movement was 218 degrees and a residual of 26,312. The alignment with the sun took 291 days and a residual of 38,126, and the number of degrees traveled was the same.
