Let's work our way through the document. The law has 66 articles in total and comes into effect on the day of publication i.e. immediately

I don't propose to translate all 66 articles; just those that strike me as particularly noteworthy. Lots to unpack. https://www.gld.gov.hk/egazette/pdf/20202444e/es220202444136.pdf
