8. Subjects with chronic HBV infection must receive HBV-DNA \< 500IU/ml and HBsAg positive patients must receive antiviral therapy according to the Guidelines for Chronic Hepatitis B Prevention and Treatment 2015 Edition. HCV-RNA positive patients must receive antiviral therapy according to the Hepatitis C Prevention and Treatment Guidelines 2015 Edition and have liver function within the normal range;
9. Recovery of AE associated with previous systemic chemotherapy, radical/extensive radiotherapy to National Cancer Institute General Adverse Event Term 5.0 (NCI CTCAE V5.0) ≤ Class 1 (except hair loss, non-clinically significant and asymptomatic laboratory abnormalities);
10. For subjects with herpes, 3 months after completion of herpes treatment;
11. Expected survival ≥12 weeks;
12. Fertile women must have a negative serum or urine pregnancy test within 7 days before the first dose. Fertile male or female patients volunteered to use effective contraceptive methods, such as dual screen contraception, condoms, oral or injectable contraceptives, and intrauterine devices, during the study period and within 90 days of the last study medication. All female patients will be considered fertile unless they have undergone natural menopause, artificial menopause or sterilization (e.g. hysterectomy, bilateral adnexectomy or irradiation of radioactive ovaries).
13. More than 4 weeks after the end of previous anti-tumor therapy (including endocrine, chemical/radiotherapy, targeted therapy) (more than 6 weeks after the treatment of nitrosourea and mitomycin chemotherapy);
14. Four weeks after major surgery;
15. At least one measurable or evaluable lesion was present according to RECIST1.1 criteria.

Exclusion Criteria:

1. A history of pleural effusion related to moderate or severe ascites, hemorrhagic esophageal varices, hepatic encephalopathy, or liver insufficiency within 6 months prior to screening;
2. Patients with large tumors - tumors \>50% by liver volume and/or invading inferior vena cava;
3. Non-recovery to National Cancer Institute General Adverse Event Term 5.0 (NCI CTCAE V5.0) level 1 toxicity (excluding hair loss, non-clinically significant and asymptomatic laboratory abnormalities) due to prior antitumor therapy prior to initial administration of the study drug;
4. Other malignancies (except basal cell carcinoma or squamous cell carcinoma of the skin and carcinoma in situ of the cervix that have been effectively controlled) in the past 5 years;
5. For subjects with known central nervous system metastases, if they have received BMS in the past and their condition is stable (no evidence of imaging progression is seen at least 4 weeks before the first administration of the trial therapy, and any neurological symptoms have returned to baseline), repeated imaging examinations confirm no evidence of new BMS or the expansion of the original BMS. Participants who do not require steroid therapy at least 14 days before the initial administration of the trial therapy are eligible to participate in the trial. Subjects with cancerous meningitis should be excluded regardless of whether they are clinically stable;
6. Received standard anti-tumor therapy for liver cancer within 4 weeks before the first drug use, including surgery, interventional therapy, systemic therapy, radiotherapy and traditional Chinese medicine therapy (the instructions for traditional Chinese medicine therapy with clear anti-tumor indications, and a one-week washout period is enough before the first drug use);
7. Received radical radiotherapy (including more than 25% bone marrow radiotherapy) within 4 weeks prior to initial medication;
8. Have previously received similar drugs for antitumor therapy;
9. Received major surgical operations (the definitions of major surgical operations refer to Grade 3 and Grade 4 operations specified in the "Measures for the Clinical Application of Medical Technology" implemented on May 1, 2009) or unhealed wounds, ulcers and fractures within 4 weeks before the first drug use;
10. The subjects currently have active gastric and duodenal ulcers, ulcerative colitis and other digestive tract diseases, or active bleeding from unexcised tumors, or other conditions determined by the researchers that may cause digestive tract bleeding and perforation;
11.

13. Severe and uncorrectable electrolyte abnormalities determined by the investigator to be clinically significant;
14. The patient had an active infection or developed an unexplained fever (body temperature \>38.5oC) during screening and prior to initial administration;
15. Preparing for or having previously received allogeneic organ or bone marrow transplantation, including liver transplantation;
16. Subjects with a past or current history of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonia, drug-related pneumonia, or severe impairment of lung function that might interfere with the detection and management of suspected drug-related pulmonary toxicity;
17. Patients with active tuberculosis (TB) who are receiving anti-TB therapy or have received anti-TB therapy within 1 year prior to initial medication; Known human immunodeficiency virus (HIV) infection; The copy number of hepatitis B and hepatitis C virus was active.

19. Known allergy to any herpes virus and OH2 inJ ingredients;
20. Any other medical condition, clinically significant metabolic abnormality (e.g., uncontrolled diabetes, thyroid dysfunction), physical abnormality, or laboratory abnormality, in which, in the investigator's judgment, there is reason to suspect that the patient has a medical condition or condition unsuitable for the study drug (e.g., the presence of epileptic seizures and the need for treatment), Or it could affect the interpretation of the findings, or put patients at high risk.
21. Received the corresponding experimental drugs in clinical trials of other unapproved or unmarketed drugs within 4 weeks before the first drug use;
22. As determined by the investigator, the subjects had other factors that might have led to the forced termination of the study.
