1. Prospective, randomized, multicenter clinical study
2. This is a post-marketing clinical study to evaluate whether it will affect the safety event when it is used in different treatment ways. Adopting non - inferiority design, 2700 cases were enrolled.
3. EDC system (eCRF electronic data collection system)
4. Follow-up points: 30 days,3 months, 12 months, 24 months, 36 months, 48 months and 60 months after the operation;

1. Subjects are eligible for coronary intervention
2. The lesion needs to be pre-expanded or special circumstances should be carefully considered according to the clinical manifestations
3. The selection of target vessel is based on the criteria of a diameter between 2.25mm and 4.0mm
4. If a stent needs to be placed at the target vessel, it is recommended that there be at least 2mm overlap between the stents; if the stent expansion is not sufficient, post-dilatation treatment is required.

5. There are other diseases such as cancer, malignant tumor, congestive heart failure, organ transplant, or candidate) or has a history of abuse (alcohol, cocaine, heroin, etc.), plan adherence is poor, or the life expectancy of less than 1 year;
6. It is estimated that elective surgery patients within 12 months;
7. Other coronary lesions requiring staged intervention;
8. If there are branches of blood vessels that need to be treated, the diameter of blood vessels ≥ 2.5 mm;
9. The subject's compliance or the researcher's judgment was not suitable for the participants in the study;
10. Pregnant or lactating persons; Imaging criteria

1. Left main disease, transplanted vessel lesions, stent restenosis; 2. The balloon cannot be predilated or/or the severe calcification lesion of rotatory failure; 3. The distortion of the stent is difficult to pass;
