Many thanks to the person who shared that you can ask your local Chinese embassy for a copy of „The Governance Of China“.
I reached out to the Chinese embassy in Vienna and got not only a super friendly response, but also an invite to the embassy + 6 copies of the German translation (2x II, III, IV)!
I’m well aware of the history and effect the Opium and other hard drugs have had on China and understand why that’s lead to their current policy.
I was talking about weed specifically with my comment but should have been clearer.
Edit: Also again I’m not expecting them to change policies just for my personal preferences, the majority of people there support the policy so I respect that
About cannabis specifically i agree with you. But given China's history i also can't fault them for choosing to be cautious.
