Brief summary: This is a single arm and open-label phase I trial to evaluate the safety, tolerability and efficacy of the oncolytic virus M1 （M1-c6v1）(iv 1×109 CCIC50, 1 dose per day, on day 1-5 each 28 day cycle) combined with anti-PD-1 antibody SHR-1201 (iv, 200 mg, once every two weeks) and Apatinib (po. 250 mg qd ) in the patients with advanced/metastatic hepatocellular carcinoma. 10 participants will be sequentially enrolled. The treatment duration is 12 months. All patients continue combination treatment until disease progression, unacceptable toxicity, death, or discontinuation for any reason.

   ④ Coagulation function: International Normalized Ratio (INR) or Activated partial thromboplastin time (APTT) ≤ 1.5×ULN
10. Reproductive subjects (male and female) must agree to use effective birth control measures with their partners for at least 180 days after the last medication.
11. Volunteer to participate in clinical research; fully understand and be able to sign the informed consent form (ICF); willing to follow and have the ability to complete all trial procedures.

Exclusion Criteria:
