Expected survival time \>=12 weeks; 9. Laboratory values within 3 days before the first dose meet the following requirements:
• Blood routine examination: (except for hemoglobin, no blood transfusion within 2 weeks prior to screening, no granulocyte colony-stimulating factor \[G-CSF\], no medication correction):
• <!-- -->
• Absolute neutrophil count \>=1.5×10\^9/L;
• Platelets \>=75×10\^9/L;
• Hemoglobin \>=90 g/L; (2) Biochemical examination:
• <!-- -->
• Serum albumin \>=30g/L;
• Serum total bilirubin \<=1.5×ULN;
• ALT and AST \<=3×ULN;
• Serum creatinine \<=1.5×ULN; or Cr clearance \> 50 mL/min (3) International normalized ratio (INR) \<=1.2 or prothrombin time (PT) above the range of normal controls \<=2 seconds; (4) Urine protein \<2 (if urine protein \>=2, 24-hour (h) urine protein quantification can be performed, and 24-hour urine protein quantification \<1.0g can be enrolled); 10. If you have hepatitis B virus (HBV) infection, such as HBsAg positive, HBV-DNA needs to be tested, and HBV-DNA needs to be \< 2000 IU/mL (if the study center only has copy/mL testing units, it must be \<104 copy/mL); For subjects with HBV-DNA\>=2000 IU/mL, receive at least 1 week of antiviral therapy (only nucleosides such as entecarvir, tenofovir fumarate, and propofol tenofovir fumarate tablets) are allowed, and viral copy number decreases by more than 10 times (1 lg) compared to before the first dose. For HBV-infected patients, antiviral therapy is required throughout the study. Hepatitis C virus (HCV)-RNA-positive subjects must receive antiviral therapy as per treatment guidelines; 11. Women of childbearing age must have a negative pregnancy test (βHCG) before starting the first dose. Women of childbearing potential and men (who have sex with women of childbearing potential) must agree to use contraception during treatment and for 6 months of the last dose.

You may not qualify if:

• \. Known cases of fibroblastic layer HCC, sarcomatoid HCC or mixed-type cholangiocarcinoma and HCC; 2. Prior to the first dose of the study treatment, there was toxicity that did not recover to the 5.0 version of the National Cancer Institute Common Toxicity Criteria (NCI CTCAEv5.0) level 1 (excluding hair loss, non-clinically significant and asymptomatic laboratory abnormalities); 3.
