Treatment with an approved TKI, used for > 3 years. 4. Molecular findings in units with stable CF values: maintenance of stable molecular biological response above efficacy (MMR; 1 year. 5. Patients are voluntary patients who voluntarily agree to participate in this trial and sign the informed consent form after fully understanding the nature of the trial, the purpose of the trial, the expected possible benefits and possible risks, and the relevant results of previous studies. 6. For patients who have previously reduced their dose, they can still be enrolled if they meet the conditions, and the total reduction time is 24 months, and they can voluntarily enter the discontinuation phase or continue to maintain the reduced dose after 24 months of reduction.

Exclusion criteria: 1. Patients who have received prior hematopoietic stem cell transplantation or immune cell therapy; 2. Other conditions deemed by the investigator to be inappropriate for participation in clinical observation; 3. Participation in another clinical trial within 4 weeks prior to the start of this study.
