Inclusion Criteria: * Patients who meet any of the following criteria are not allowed to enter the test: 1. Aged between 18 and 75 years old, no gender restriction; 2. According to "Primary Liver Cancer Diagnosis and Treatment Standard." (2011 Edition) issued by the National Health and Family Planning Commission, advanced or metastatic hepatocellular carcinoma patients who diagnosed by pathology /cytology fail to undergo liver surgery and/or other local treatment (ablation or hepatic artery intervention), or have recurrence and progression after surgery and/or other local treatment; 3.

The central laboratory must receive specimen of tumor tissue (wax block or white slice) at first, and detect the PD-L1of tumor tissues by immunohistochemistry, only positive expression of PD-L1 in immune cells can be enrolled; 5. According to the evaluation criteria of solid tumor reaction (RECIST 1.1), it has at least one measurable target lesion (Non-lymph node lesions with the longest diameter larger than 10mm, lymph node lesions with the short diameter larger than 15mm); the lesions previously received local treatment such as ablation or hepatic artery interventional therapy should be detected by computed tomography (CT) / magnetic resonance imaging (MRI) and according to RECIST1.1, It's sure that disease progression has occurred and the longest diameter is more than 1.0cm,it can be used as a measurable target lesions; 6. Liver surgery was performed more than 3 months ago, ablation or interventional treatment of hepatic artery was performed more than 4 weeks ago, and the adverse reactions returned to normal; After surgery or other local treatment, if patients have gone beyond the norm for systemic adjuvant chemotherapy or sorafenib, it will need more than 6 months after the chemotherapy or sorafenib, and disease progression and / or metastasis have occurred; 7. The Child-Pugh score of liver function is grade A or better grade B (score≤7); 8. The ECOG score of physical condition is 0-1; 9. Expected survival time≥12 weeks; 10. 2 weeks before the first medication of the trial, there is no use of modern Chinese medicine preparation with liver cancer indication, including Delisheng injection, Kanglaite injection/soft capsule, Aidi injection or Cotside injection, elemene injection/oral liquid, Huaier granule, cinobufotalin and GanFuLe capsule / tablet and so on. 11. The function of the main organs is basically normal and meets the following requirements: ① Marrow: Absolute neutrophil count≥1.5×109/L, platelet≥80×109/L, hemoglobin≥90g/L; ② Liver: Total bilirubin≤1.5 times of the upper limit of normal(ULN), Aspartate aminotransferase (AST) and alanine aminotransferase (ALT)≤5 × ULN; albumin≥29g/L; ③ Kidney: Serum creatinine≤ 1.5 x ULN, or creatinine clearance rate≥ 50ml/min; 12. If HBV-DNA≥104 copies/ml(2000IU/ml), antiviral therapy must be done first, the patient can be included in the group until HBV-DNA\<104 copies /ml(2000IU/ml); and continue to take antiviral drugs, monitor liver function and hepatitis B virus load; 13. Women of childbearing age must receive pregnancy tests 14 days before treatment and the results are negative; Men and women must take effective contraceptive measures during the trial (from signing an informed consent to 3 months after the last medication); 14. Patients volunteered to join the study, sign the informed consent, have good compliance and cooperate with follow-up; 15. The subjects do not participate in other clinical trials within 4 weeks before screening; If the subject fails in other test screening, but meets the requirements of this test, then can be enrolled. Exclusion Criteria: * Patients who meet any of the following criteria are not allowed to enter the test: 1. Imaging examination shows that HCC liver tumors are huge (≥60% of the liver volume), or cancer embolus of portal trunk (occupying ≥50% of the vascular diameter), or cancer embolus invading mesenteric vein or inferior vena cava; 2. Middle or higher ascites which is clinically significant, it requires therapeutic abdominal paracentesis /drainage, or the Child-Pugh score \> 2; 3. Local anticancer therapy (including surgery, ablation, hepatic arterial chemotherapy, embolization or radiotherapy) or major surgery was performed 28 days prior to randomization; 4. Hepatocholangiocarcinoma and fibrolamellar cell carcinoma; In the past or at the same time, there were other cancers whose primary site or histology are entirely different from hepatocellular carcinoma, except cervical carcinoma in situ, previously treated basal cell carcinoma and superficial bladder tumor (Ta, Tis, T1); Patients with other malignancies who have been cured for \>5 years prior to enrollment may be admitted to the group; 5. Pregnant or lactating women; 6. Patients who have high blood pressure and failed to receive good control with antihypertensive drugs (systolic blood pressure \>140mmHg, diastolic pressure \>100mmHg); Patients suffer from CTCAE classification type II or above myocardial ischemia or myocardial infarction, poorly controlled arrhythmia; and/or New York Heart Association(NYHA) grade III to IV cardiac dysfunction. 7. Allograft transplants including liver transplantation were performed previously, or a liver transplant was planned during the trial; 8. Hepatic encephalopathy and / or hepatic nephropathy occurred within 6 months; 9. Patient with active hepatitis C, that is, anti -HCV positive or HCV-RNA positive and abnormal liver function; 10. Human immunodeficiency virus (HIV) tests are positive or severe infection requiring systemic treatment with antibiotics; 11. Inability to swallow, chronic diarrhea or intestinal obstruction that significantly affecting medication intake and absorption; 12. Having a history of digestive tract bleeding within 6 months, or with a clear gastrointestinal bleeding tendency, including local active ulcerative lesions, positive fecal occult blood; 13. The patient has or is suspected to have known active autoimmune disease; 14. If a central nervous system metastasis is known and a metastasis of the central nervous system is suspected, the cranial MRI examination should be performed to exclude it; 15. Abnormal coagulation function: prothrombin time (PT) \>16S or international normalized ratio (INR) \>1.5; 16. There is a history of schizophrenia or psychotropic substance abuse; 17. Known to be allergic or intolerant to Icaritin or sorafenib and excipients; 18. Other conditions that researchers believe discourage patients from participating in trials.
