Why do UK students studying abroad have to cherish London for a lifetime?

Samuel Johnson, the British writer, once said, "If a man is tired of London, he is tired of life." There's a saying circulating on the Chinese internet that goes, "Those who study in the UK for a year will spend a lifetime reminiscing about London." I'm curious, what exactly makes London so charming? Did 24fall's treasure, 🈶️, go there? Feel free to reach out to me for group organization at my 🏠. Let's all be happy every day together!
