How to quickly integrate into Singapore life?

In fact, integration means accepting assimilation, respecting local culture, learning local accent, accepting local food taste, dressing according to local fashion, and most importantly, making friends with local people. I know many friends who have been in Singapore for two or three years, and I can't tell whether I am from Singapore or China. They have successfully integrated into Singapore, and all their friends are locals. There are also many people who have been here for more than ten years and still speak with a northeast accent. They must eat with Sichuan flavor, and their friends are all from China, so they will never blend in. This is why children are easier to integrate than adults, because there is no contradiction between them. Besides, among all countries in the world, Singapore is the most friendly country to China people. If one cannot integrate in Singapore, it is even more impossible to integrate in other countries. There are many such people around us who have lived in Shanghai or Beijing for more than ten years and can't even speak the local dialect. You don't think he can fit in? In fact, he is resisting integration.
