Inclusion Criteria: 1. With the patient's explicit consent and after signing the informed consent form, the patient is willing and capable of complying with the planned visits, research treatments, laboratory tests and other trial procedures; 2. Age range: 14 to 65 years old. Both men and women are eligible; 3. All types of CD7+ T-cell non-Hodgkin's lymphomas (except T-lymphoblastic lymphoma) diagnosed according to the World Health Organization's classification of hematopoietic and lymphoid tissue tumors (2022); 4. For patients with T-cell lymphoma who are refractory to the first-line chemotherapy regimen or who experience recurrence and resistance after at least the second-line chemotherapy regimen. The following criteria must be met: a. For those patients who had only received first-line treatment previously, if they did not achieve PR after at least 4 cycles of the first-line regimen, or if they did not achieve CR after at least 6 cycles of the first-line regimen; b. Those who experienced recurrence in the early stage (\< 12 months) after complete remission; or those who experienced recurrence in the late stage (≥ 12 months) and did not achieve remission after one course of standard induction chemotherapy; c. Those who have not achieved remission after treatment with second-line or more chemotherapy regimens; 5. During the enrollment screening process, the subjects were confirmed to have CD7+ (with CD7 expression ≥ 10%) through pathological histology and/or cytology; 6. Having measurable or evaluable lesions: The target lesion is defined as a lesion within lymph nodes with a long diameter of ≥ 15mm, or an extranodal lesion larger than 10mm (in accordance with the Lugano 2014 criteria); Lesions that have received prior radiotherapy are considered measurable only if there is a clear progression after completing radiotherapy; or PET-positive lesions determined according to the Lugano criteria; 7. The Eastern Cooperative Oncology Group (ECOG) performance status score is 0 to 2, and the estimated survival period is greater than 3 months; 8. Having appropriate organ functions: a. The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) should be ≤ 3 times the upper limit of normal (ULN). If the abnormality of ALT and AST is judged to be caused by the disease (such as liver infiltration or bile duct obstruction), the thresholds can be relaxed to ≤ 5 times ULN; b. Total serum bilirubin ≤ 2 times ULN, except in cases where Gilbert syndrome is present; patients with Gilbert syndrome whose total bilirubin is ≤ 3 times ULN and direct bilirubin is ≤ 1.5 times ULN can be included; c. Serum creatinine ≤ 1.5 times the upper limit of normal, or creatinine clearance rate ≥ 60 mL/min; d. The international normalized ratio (INR) is no more than 1.5 times the upper limit of normal (ULN), and the activated partial thromboplastin time (aPTT) is no more than 1.5 times the ULN; e. Having the lowest level of lung reserve, defined as ≤ grade 1 dyspnea (CTCAE v5.0) and a blood oxygen saturation of ≥ 92% in the absence of oxygen supplementation; f. Left ventricular ejection fraction in echocardiography is ≥ 50%; no clinically significant abnormal electrocardiogram findings; no clinically significant pericardial effusion or pleural effusion. 9. Female participants of childbearing potential must have negative blood/urine pregnancy tests within 7 days prior to infusion. All sexually active males and females with reproductive capacity must agree to use highly effective contraception throughout the study and for at least 2 years after administration of the investigational treatment. Exclusion Criteria: 1. Severe cardiac insufficiency with left ventricular ejection fraction (LVEF) \<50%； 2. Documented history of severe pulmonary impairment； 3. History of organ transplantation or active graft-versus-host disease (GVHD); 4. Concurrent other progressive malignancies; 5. Uncontrolled severe infections; 6. Severe autoimmune diseases or primary immunodeficiency disorders; 7. Positive for any of the following: Hepatitis B surface antigen (HBsAg) and/or hepatitis B e antigen (HBeAg); Hepatitis B e antibody (HBe-Ab) and/or hepatitis B core antibody (HBc-Ab) with HBV-DNA levels above the upper limit of normal (ULN); Hepatitis C virus antibody (HCV-Ab) with detectable HCV RNA; Human immunodeficiency virus antibody (HIV-Ab); Treponema pallidum antibody (TP-Ab); Cytomegalovirus (CMV) DNA above ULN; Epstein-Barr virus (EBV) DNA above ULN； 8. History of severe hypersensitivity to biological products (including antibiotics); 9. Pre-existing central nervous system disorders, including but not limited to: Uncontrolled epilepsy；Cerebral ischemia/hemorrhage；Dementia；Cerebellar disorders； 10. Previous recipients of autologous or allogeneic hematopoietic stem cell transplantation; 11. Any other severe physical or psychiatric conditions or significant laboratory abnormalities that may: Increase study participation risks；Interfere with study results interpretation; Be deemed by investigators to render the patient unsuitable for study participation; 12. Presence of lymphoma-related clinical emergencies requiring immediate intervention at screening due to tumor mass obstruction or compression (e.g., intestinal obstruction, vascular compression, etc.).
