My understanding (but happy for more information if anyone has it) on the oestrogen thing, is China in the last few years increased restrictions on pharmaceutical medications across the board. Previously you could buy most non addictive (opiates, benzos et) online without any prescription. Antibiotics. Blood pressure medication, whatever. This is included oestrogen. They would also ship these overseas.

Now it’s harder because you need a prescriptions and there’s other rules. So it wasn’t so much some officials saying “How do we make trans people’s lives harder” but more them bringing what had been a rather laissez-faire situation into regulations more in line with most other countries in the world (Europe, Asia etc). But it did materially affect trans people in China and globally.
