Is type nine personality fixed? Is a person's character once determined, it will never change? Can you change from marginal personality to core personality?

In fact, you already have all nine personalities. If you find all of them after learning the Nine Forms, it means that you haven't really understood the Nine Forms, but this is normal. You and I both have nine elements of personality types, but only one of them is your or my main personality type. The main personality types we belong to dominate our thinking and behavior responses. We can show various personality types in the simple behavior of individuals, such as ambition, happiness, anger, fear and diligence. If we observe carefully, we can find that everyone's behavior characteristics are different from our main personality types. The sense of humor of personality type one is different from that of personality types two, three and four. We will find that all personality types have different attitudes towards work. We need to comprehensively analyze everyone's attitude, emotions and motives, and then we will clearly find that our main personality type is the pattern that habitually dominates our lives.
