PS. There is another aspect that interests me in the attached photo to the article. The photo shows that Zheng is obviously taller than Ma, but both of their official heights are the same: 178cm. The plausible explanation may be that Zheng was wearing a pair of high-heeled sneakers, but she would not. Therefore, the only explanation is that Ma’s height has shrunk due to aging. FYI, I used to be 168cm, but now I am pushing 80, and my height has shrunk to 166.2cm.
