Inclusion Criteria * Patients must meet all of the following criteria to be eligible for the study: 1. Voluntarily participate in the clinical study. The individual or the legal guardian fully understands the study, sign the informed consent form (ICF), and is willing and able to follow and complete all trial procedures. 2. Age ≥ 14 years and \< 70 years. 3. Subjects with refractory or relapsed disease after current standard treatments (including allogeneic or autologous hematopoietic stem cell transplantation) who are not suitable for other treatment options, such as a second stem cell transplant. The definitions of relapsed/refractory lymphoma include one of the following situations: 1. No response to first-line treatment (primary refractory disease, excluding participants intolerant to first-line treatments). * Disease progression (PD) as assessed after first-line treatment. * Best efficacy of first-line treatment (e.g., 4 cycles of RCHOP) as stable disease (SD), with the duration of SD not exceeding 6 months after the last dose. 2. No response to second-line or more treatments. * PD being the best response to the most recent treatment. * Best efficacy of the last line of treatment as SD after at least 2 cycles, with the duration of SD not exceeding 6 months after the last dose. 3. Refractory after autologous stem cell transplant (ASCT). * Disease progression or relapse ≤ 12 months post-ASCT (relapsed patients must have biopsy-proven relapse). * If salvage treatment is administered after ASCT, the subjects must not have had a response or relapse after the last line of treatment. * Relapsed or refractory disease after two or more lines of systemic treatment. 4. Lymphoma patients must have target antigens meeting the following criteria: 1. CD20/CD30 double-positive expressing lymphoma. 2.

Laboratory tests during screening must meet the following requirements, and the hematological assessment must not have received cell growth factors within 7 days (long-acting colony-stimulating factors (G-CSF/PEG-CSF) require a 2-week interval) or platelet transfusions: 1. Absolute neutrophil count ≥ 1.0×10\^9/L. 2. Hemoglobin ≥ 60 g/L (without red blood cell transfusion in the last 7 days). 3. Platelets ≥ 50×10\^9/L (unrestricted for CLL indications). 4. Total bilirubin ≤ 1.5× the upper limit of normal (ULN); or total bilirubin ≤ 3× ULN when the tumor invades liver tissue. 5. Aspartate transaminase (AST), alanine transaminase (ALT) ≤ 2.5×ULN, with AST/ALT ≤ 5×ULN when the tumor invades liver tissue. 6. Creatinine \< 1.5× ULN and estimated creatinine clearance ≥ 60 mL/min. 10. Ejection fraction ≥ 45%, with echocardiogram (ECHO) confirming no pericardial effusion (excluding small or physiological amounts), and electrocardiogram results with no clinical significance. 11. Baseline oxygen saturation \> 92% without supplemental oxygen. 12. Women of childbearing potential must have a negative serum or urine pregnancy test result (women who have undergone surgical sterilization or have been postmenopausal for at least 2 years are not considered of childbearing potential). Exclusion Criteria: * Subjects are not eligible to participate in this study if they meet any of the following criteria: 1. MRI of the brain shows evidence of central nervous system lymphoma; active primary central nervous system DLBL, unless central nervous system involvement has been effectively treated (i.e., participant is asymptomatic), and there has been more than a 4-week gap since local treatment. 2. Active central nervous system diseases, such as epilepsy, cerebrovascular ischemia/hemorrhage, dementia, cerebellar diseases, or any autoimmune diseases with central nervous system involvement. 3. History of or concurrent diagnosis of malignancies other than CD19+ malignancies. 4. Clinically significant heart disease or arrhythmias that cannot be controlled with medication. 5. Presence or suspicion of fungal, bacterial, viral, or other infections that are uncontrolled or require intravenous antibiotics for treatment; uncomplicated urinary tract infections and uncomplicated bacterial pharyngitis are allowed. 6. Positive for hepatitis B (HBsAg positive and HBV DNA \>1000 copies/mL) and hepatitis C (positive for HCV antibodies); syphilis or human immunodeficiency virus (HIV) infection. 7. Presence of any indwelling catheter or drainage tube (such as percutaneous nephrostomy, indwelling Foley catheter, bile drainage tube, or pleural/peritoneal/pericardial catheter); use of specialized central venous access devices like Port-A-Cath® or Hickman® catheters is allowed. 8. History of using any of the following medications: 1. Lenalidomide within 1 day before the apheresis. 2. Idelalisib (oral PI3Kδ inhibitor) within 2 days before the apheresis. 3. Short-acting targeted therapy (like tyrosine kinase inhibitors) within 72 hours before the apheresis. 4. Venetoclax (BCL-2 inhibitor) within 4 days before the apheresis. 5.

Radiation therapy within 14 days before enrollment. 8. Systemic cytotoxic drugs, including low-dose maintenance chemotherapy (cyclophosphamide, ifosfamide, bendamustine, methotrexate, or mercaptopurine, vincristine, etc.), within 14 days before enrollment.
