Fathomless Numbers (continued)

Note added on June 22, 2022

The CCP top leader who ordered People’s Liberation Army, to suppress the peaceful student demonstration in Beijing, with all costs, with guns and tanks, turning the whole thing into a massacre, was Deng Xiaoping.

In our study here based on published data on Wikipedia, we find that there are some personal traits in Deng Xiaoping which are mathematically linked to those of Mao Zedong, another ruthless CCP top leader, popularly known as Chairman Mao.

Date of birth of Deng Xiaoping is August 22, 1904, or DOB = 8221904.

Cross sum of this DOB is 26, or CS(DOB)=26.

Date of death of Deng Xiaoping is February 19, 1997, or DOD = 2191997.

Cross sum of this DOD is 38, or CS(DOD)=38.

Thus

CS(CS(DOB)) + CS(CS(DOD)) = 2+6+3+8=19 whose cross sum is 10 whose cross sum is 1.

Let us now study Mao Zedong.

Date of birth of Mao Zedong is December 26, 1893, or DOB=12261893.

Cross sum of this DOB is 32, or CS(DOB)=32.

Date of death of Mao Zedong is September 9, 1976, or DOD=991976.

Cross sum of this DOD is 41, or CS(DOD)=41.

Performing the same computation, we obtain

CS(CS(DOB)) + CS(CS(DOD)) = 3+2+4+1=10 whose cross sum is 1.

This agreement between Deng and Mao is incredible!

As a comparison, let us also consider the examples of two other people in the top leadership of CCP in the history of the June 4^th Massacre, Hu Yaobang and Zhao Ziyang.

Date of birth of Hu Yaobang is November 20, 1915, or DOB=11201915.

Cross sum of this DOB is 20, or CS(DOB)=20.

Date of death of Hu Yaobang is April 15, 1989, or DOD=4151989.

Cross sum of this DOD is 37, or CS(DOD)=37.

So

CS(CS(DOB)) + CS(CS(DOD)) =2+0+3+7=12 whose cross sum is 3.

Date of birth of Zhao Ziyang is October 17, 1919, or DOB=10171919.

Cross sum of this DOB is 29, or CS(DOB)=29.

Date of death of Zhao Ziyang is January 17, 2005, or DOD=1172005.

Cross sum of this DOD is 16.

Hence

CS(CS(DOB)) + CS(CS(DOD)) = 2+9+1+6=18 whose cross sum is 9.

Therefore, we see that the personal traits of Hu Yaobang and Zhao Ziyang based on the cross-sum calculations from their dates of births and deaths are in total disagreement against that of Deng Xiaoping and Mao Zedong, although those of Hu and Zhao share a nontrivial common divisor.

In summary, we come up with

Personal Traits Mystery

The examples shown demonstrate that calculations on the cross sums of the dates of births and deaths could give out common as well as disputative characteristics of top political leaders.

In short, in addition to their shared common characteristics in history and social activities, Deng and Mao have the same personal traits now calculated from their dates of births and deaths.  In contrast, Hu and Zhao do not share the common traits of Deng and Mao, although the personal traits of Hu and Zhao are found to share a significant portion in the form of a nontrivial common divisor.

It remains another unexplained puzzle why the number of Hu Yaobang, which is 3, is a prime and only factor of that of Zhao Ziyang, which is 9.
