Hi, my name is Nigel. I graduated from Nanjing University of Aeronautics and Astronautics and began my career designing rocket components for China’s aerospace program. So unlike the so-called “rocket scientists” on Wall Street, I am the real deal. For the past 20 years, I have helped foreign businesses achieve a smooth landing in China, navigating everything from market strategy and regulatory compliance to local partnerships and execution. I speak the languages of engineering, mathematics, and cross-border business. Let us have a cup of tea at a peaceful Buddhist temple and talk business. We can brainstorm practical, real-world approaches to doing business in China. My associate and I also host business networking events and organize trips around China for professionals and entrepreneurs. Please add the WhatsApp contact above to connect and confirm details.
