Wow! Good find!
And guess what ... the Chinese, with their one-child-per-family policy of abortion have been selectively breeding for males. Not enough females have been allowed to live. This can’t end up well. God help us.
It should end up very well. Fewer females, with a desire for a low birthrate should be the saving of China, by reducing their 1 1/2 billion population down to a survivable size in a century or two. Less fighting for resources with us and others, good result.
