Resigned from a big company in Nanjing and wanted to start a business. I don't know Feng Shui and I don't know the Book of Changes. Any suggestions?

82 years, the age of starting a business. Fengshui or Yijing numerology can provide some reference for people. I am a 79-year-old entrepreneur who has been in business for many years. I feel that in the process of company development and personal development, I sometimes encounter some headaches. Sometimes I can't analyze the business, and I will talk to my friends. Sometimes I can really provide some useful suggestions from the perspective of enterprise development. My friend's surname is Fang, and he is in Nanjing. His level is good.
