When you buy an asset for 10 yuan and the price drops to 8 yuan, panic begins to set in; at 6 yuan, you still choose to hold; as it further slides to 5 yuan, you are left numb and lose interest in the market. Yet when the price rises back to 7 yuan, you pay no attention; returning to 8 yuan, your heart stirs with the impulse to buy; when it rises back to 10 yuan, you hesitate and miss the good entry opportunity; it falls back to 8 yuan, and you regret not selling at a high.

Eventually, the price touches 10 yuan again, and you decisively sell. Not long after, the price skyrockets to 12 yuan, 20 yuan, and even 40 yuan. Seeing others make a fortune, you rush to enter at a high. Looking back over the past decade, it is not hard to see that most people always enter at the peak of a bull market and cling to the bottom of a bear market, waiting for the market to recover, only to hastily exit as soon as they break even, and then recklessly jump in at new highs. This behavior exemplifies the cyclical nature of humanity—fear and greed intertwining, hope and despair cycling.

The intrinsic logic of the market lies in cyclical fluctuations. Only those who deeply understand the 'Dao' of the market can perceive human weaknesses and anticipate market cycles. Only by mastering this key can we progress steadily on the investment path, not blindly follow the crowd, not make rash decisions, thereby advancing steadily and far.
