Chinese got the rice culture from SE Asian people e.g. Tai-Kadai, who at that time inhabited S China.
From Ricepedia:
"Recent genetic evidence show that all forms of Asian rice, both indica and japonica, come from a single domestication event that occurred 8,200–13,500 years ago in the Pearl River valley region of China."
Indentation by tab is good for shallow data or code e.g. Python. Space is bad. For deeper levels, I'd go for a visible, countable symbol
Level 1

For the record, "Wuhan Pneumonia" and "Wuhan Virus" were widely used by official news coverage in Taiwan, Hong Kong, and guess what, Mainland China, before the WHO suddenly dictated all people must use "Covid-19" or else you're racist or propagandist.
This trick is very effective in erasing the obvious link between the virus and its origin.
Conway's Game of Life was my first and always is my favorite thing to be programmed (the runner ups are the Mandelbrot set and strange attractors), to the point that I messed around with its rules and became the continuous CA you see at the bottom of the blog post.
And the technologies and science have changed a lot. It was Pascal and Assembly and maybe BASIC in my first try, now it's Python, TensorFlow, WebGL etc. Back then I know nothing about the theory of complex systems, it turns out that the Game of Life and a whole bunch of fascinating emergent systems are at the crossroads of complex systems, artificial life, and artificial intelligence research (see Neural CA, CA-NEAT, etc).
As for Conway's resentment of his own creation, I was told that his friend showed the continuous CA to Conway last year, and he was mesmerized by its complexity. I hope that means the great mathematician was delighted by the direct offspring of his brainchild that he was once ashamed of.
