Inclusion Criteria: 1. They are voluntary to sign an informed consent form, agree to follow and have the ability to complete all trial procedures with knowledge of the study; 2. Male or female, aged ≥18 and ≤ 75 years; 3. Patients with refractory or recurrent lymphoma diagnosed according to the 2016 WHO classification criteria; the relapsed, refractory lymphoma is defined as follows: Relapse is considered to occur when a new lesion appears at the primary site or elsewhere when response has been achieved with at least one current standard or commonly used regimen; Lymphoma is considered refractory if one of the following conditions is met: Less than 50% tumor shrinkage or disease progression occurs after ≥4 cycles of treatment with current standard or commonly used regimens; Patients who have achieved partial or complete response by current standard or commonly used regimens and relapsed within six months after termination of treatment; 4. There is at least one measurable or evaluable tumor lesion (preferentially enrolled the measurable lesions), measurable lesions: lymph nodes with longest diameterof ≥15 mm, metastatic lesions (≥10 mm) at other sites; lesions previously treated with local therapy such as radiotherapy are considered measurable lesions if disease progression has been demonstrated; 5. Patients with a performance status score of 0\~2 according to the Eastern Cooperative Oncology Group (ECOG) scale; 6. Expected life expectancy of at least 3 months; 7. If prior anti-tumor therapy has been received , the interval to the first dose in this study should meet the following conditions: Those who have used chemotherapy drugs previously need to discontinue for more than 4 weeks.Those with a history of surgery, targeted therapy (including anti CD20 monoclonal antibodies such as rituximab; CD30 monoclonal antibodies such as Brentuximab Vedotin), therapy with anti tumor indications, and palliative radiotherapy should discontinue the treatment for more than 4 weeks;Those with prior CAR-T cell therapy or PD-1/PD-L1 monoclonal antibody therapy need to discontinue for at least 8 weeks;And they have recovered from toxic reactions to previous treatment to grade ≤ 1 identified by the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) v5.0 (NCI CTCAE v5.0) (except for residual alopecia). 8. Suitable organs and hematopoietic functions are available. Absolute neutrophil count (ANC) ≥1.0×109/L (no use of short-acting leucopenia drugs within 1 week or no use of long-acting leucopenia drugs within 3 weeks). Patients have not received platelet transfusion within 1 week; platelets ≥75×109/L (without bone marrow infiltration)/ ≥50.0×109/L (with bone marrow infiltration). Patients have not received red blood cell transfusion within 2 weeks; hemoglobin ≥90 g/L (without bone marrow infiltration)/ ≥70 g/L (with bone marrow infiltration).

Male subjects and female subjects of childbearing age should agree to take effective contraceptive measures from the time they sign the informed consent until 6 months after the last dos Exclusion Criteria: 1. Patients with any of the following cannot be enrolled: previous allogeneic hematopoietic stem cell transplantation and other organ transplantation; a history of autologous hematopoietic stem cell transplantation for not more than six months. 2. Patients have participated in clinical trials of other drugs or medical devices within 4 weeks prior to the first dose of this study; 3. Presence of central nervous system metastatic lesion; 4. Patients with previous or current other malignancies (except cured stage IB or lower grade cervical cancer, non-invasive basal cell or squamous cell skin cancer; except other malignancies that have achieved complete response (CR) for \>5 years and have not been treated with antineoplastic therapy for 5 years); 5. Subjects with active autoimmune disease, or a history of autoimmune disease with a risk of relapse (e.g., systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, autoimmune thyroid disease, multiple sclerosis, vasculitis, glomerulonephritis, etc., see Appendix 6), or patients at high risk (e.g., those requiring immunosuppressive therapy after undergoing organ transplantation). However, subjects with the following diseases are allowed to enroll : Those with autoimmune hypothyroidism who require hormone replacement therapy only; Those with skin conditions (such as eczema, rash covering less than 10% of the body's surface) that do not require systemic treatment; 6. Patients who have undergone major surgery within 28 d prior to enrollment or who are expected to have major surgery during this study period including the 21 d screening period. 7. Subjects requiring systemic corticosteroids (at a dose equivalent to \>10 mg prednisone/d) or other immunosuppressive drugs within 14 d prior to enrollment or during the study period; the the patients meet the following conditions are allowed for enrollment: Subjects are allowed to use topical or inhaled glucocorticoids; Short-term (≤7 days) use of glucocorticoids for the prevention or treatment of non-autoimmune allergic diseases is allowed; 8. Patients with a history of arterial thrombosis or deep vein thrombosis within 6 months prior to enrollment or with evidence or history of bleeding tendency within 2 months prior to enrollment, regardless of severity; partial prothrombin time (APTT) or prothrombin time (PT) \> 1.2 × ULN; oral warfarin with an international normalized ratio (INR) \> 1.2 × ULN 9. Patients with acute lung disease, interstitial lung disease or pneumonia (except for local interstitial pneumonia induced by radiotherapy), pulmonary fibrosis, acute lung disease, etc.; 10.
