What degrees should be taken from a British school to study the British system of rule of law and freedom

In 1960s, Great Famine arising from no rule of law and no freedom brought severe consequences of tens of millions of death from starvation in China,such as in Sichuan. A system must be in place to prevent this happening again in China.

The process of dealing with pandemic and reporting COVID-19 deaths and infections in China also reflects  no rule of law and no freedom. Coverup of initial outbreak of COVID-19 is said to be fundamental cause of global pandemic. China is still covering up 1960s Great Chinese Famine.

So I want to study the British system of rule of law and freedom to make rule of law and freedom in effect for ever in China. What degrees should I take from a British school of Her Majesty?
