4. Subject has carcinomatous meningitis, or has untreated central nervous system metastases.
5. Imaging shows tumor invasion of large blood vessels or unclear demarcation from blood vessels; or the investigator judges that the patient's tumor has a high possibility of invading important blood vessels and causing fatal hemorrhage during treatment.
6. Cancerous ascites and pleural effusion with clinical symptoms, requiring puncture and drainage; or those who have received ascites, pleural effusion drainage within 14 days before the first dose of the drug.

8. Previous or current interstitial pneumonitis/interstitial lung disease (except for those with radiographic changes only), pneumonia requiring systemic treatment with glucocorticoids (such as radiation pneumonitis, etc.); Current active pneumonitis or those with severe impairment of lung function confirmed by pulmonary function tests.
9. People who are known to be allergic to bevacizumab or have had a severe allergic reaction to other monoclonal antibodies.
10. Those with active tuberculosis; Those who have been adequately treated before the first dose and have discontinued anti-tuberculosis therapy for ≥ 3 months can be enrolled.
11. Have hypertension that is not well controlled with antihypertensive medication (systolic blood pressure ≥ 150 mmHg or diastolic blood pressure ≥ 90 mmHg); Previous hypertensive crisis or hypertensive sex encephalopathy.
12. Have clinical symptoms or disease of the heart that are not well controlled.
13. Coagulation abnormalities, bleeding tendency, or those receiving thrombolytic or anticoagulant therapy are allowed to receive low-dose low-molecular-weight heparin or oral aspirin prophylactic anticoagulation therapy during the trial.
14. NCI-CTCAE v5.0 grade ≥2 bleeding events within 4 weeks prior to the first dose, including but not limited to hemoptysis (hemoptysis in a single episode ≥2mL), vaginal bleeding, gastrointestinal bleeding, etc.

17. Those who are unable to swallow tablets normally, or have abnormal gastrointestinal function, which may affect drug absorption as judged by the investigator.
18. Subjects who have had a serious infection within 1 month before the first dose, including but not limited to infectious complications requiring hospitalization, bacteremia, severe pneumonia, etc.; Subjects with any active infection requiring intravenous system therapy, or who have a progeny during the screening period, prior to the first dose 38.5°C due to unknown fever\>; Those who have used antibiotics within 2 weeks before the first dose.
19. Known history of positive human immunodeficiency virus (HIV) test; Known active hepatitis.
20. Treatment with a strong inhibitor of CYP3A4, CYP2D6, P-gp, or BCRP, \<5 drug half-lives or 14 days from the date of first dose; Treatment with the above enzyme strong inducers was 28 days \< the first dose.
21. As judged by the investigator, there are other factors that may affect the results of the study or cause the study to be terminated halfway, such as alcoholism, drug abuse, other serious diseases (such as severe diabetes, thyroid disease, spinal cord compression, superior vena cava syndrome, psychiatric diseases) that require concomitant treatment, serious laboratory test abnormalities, accompanied by family or social factors, which will affect the safety of the subjects.
