In November of 2023, during a trip to Hong Kong, I returned to Shenzhen within mainland (PRC) China. It had been many years since I last crossed the bamboo curtain and I knew not what I would find...
Even the French, Spanish, German, Dutch, Italian and Malaysian citizens can get the High speed train after HK trip no need visa enter to China for 15 days from December 1st to next year November 30th, 2024.
There's plenty I miss about the place, but having left China in 2018 I suspect if I ever went back I'd be disappointed. All the places I liked seem to have been replaced by louder, dumber versions of themselves, eg La Casa is now a noisy club
