The Reverse Culture Shock in Hong Kong

I was living a pretty low waste life in Switzerland. I had changed my entire bathroom routine to be plastic free. But when I moved here, I had this major reverse culture shock. It's not even natural for people to buy refills for detergent stuff. And then that's kind of like how the two linked together. So we started brainstorming on how we could do this. We came up with some sort of app that had already existed in the US. Would you be interested in being more sustainable? These were all questions that we had no idea because we live in a very like expat side part of Hong Kong.
