After a year, I am back to starting a business in Beijing. I hope to build a big company this time. From choosing an office location to simple renovations, I considered cost-effectiveness and time efficiency, and it will be done in about two weeks. Details still need time to organize. I recall eight years ago when I also started a small company in Beijing. At that time, I had just graduated, had modest goals, and aimed to meet basic living needs in Beijing. After working hard for five years, I achieved that. After the pandemic, all employees switched to part-time or online work. This time, I am aiming higher and definitely believe I can realize a bigger vision. The entrepreneurial focus is around AI, as this is the big trend. AI infrastructure and applications worldwide are impressive now, productivity has been transformed, and next, AI productivity will change our lifestyles or entertainment methods.
