I've been wondering, what content should be included in the economic common sense section? Things that are simple yet profound may seem unremarkable, but they are actually not easy to write well. Fortunately, I finally found an article written by the chief consultant of the Beijing Financial Management Center. The author has over 15 years of experience in asset management and currently manages international funds and Chinese capital worth approximately billions of RMB in Beijing. His writing is highly enlightening and closely relates to the actual situations of ordinary investors, so I'm posting it here. This can also be considered as the first step of a thousand-mile journey.
