He emphasized that the core of portfolio design is not to pursue maximum returns, but to ensure that the principal can be protected in a crisis. The article shares the specific construction methods of a safe-haven portfolio and the "life-saving investment rules", pointing out that the key lies in "being able to afford to lose" rather than "making the most money".
