Inclusion Criteria: * 1\. Phase Ib Dose-escalation Part : Patients with histologically or cytologically confirmed unresectable locally advanced (stage IIIB and IIIC) or metastatic (stage IV) NSCLC (according to the eighth edition of the AJCC lung cancer staging criteria) who have disease progression or intolerance after previous systemic treatment. Specific treatment requirements are as follows: * Patients with EGFR sensitive mutations: They must have received EGFR-TKI treatment. If only first/second-generation EGFR-TKIs were used, T790M negativity must be confirmed. * Patients with other EGFR mutations such as EGFR exon 20 insertion: They must have received platinum-based chemotherapy. Phase Ib Dose-expansion part and Cohort 1 of Phase II: Patients with histologically or cytologically confirmed unresectable locally advanced (stage IIIB and IIIC) or metastatic (stage IV) NSCLC (according to the eighth edition of AJCC staging) who have not received previous systemic treatment or have received systemic treatment. Cohort 2 of Phase II: Patients with histologically confirmed resectable stage II-III NSCLC (according to the eighth edition of AJCC staging) who have not received previous systemic treatment; among them, N2 is defined as single-station mediastinal lymph node non-bulky metastasis (lymph node short diameter \<2 cm) confirmed by imaging and pathology, with expected complete resection. * 2\. Previous tumor tissue or pleural effusion or blood sample confirmed positive for EGFR mutation. * 3\. Measurable lesions at baseline according to RECIST 1.1 criteria. * 4\. Eastern Cooperative Oncology Group (ECOG) performance status score of 0 to 1. * 5\. Estimated life expectancy is more than 12 weeks. * 6\. It has been medically evaluated and determined that the organ functions are good (within 7 days before the first study drug administration), including: * hematological : absolute neutrophil count (ANC) ≥ 1.5 × 109/L, hemoglobin ≥ 90 g/L, platelets ≥ 100 × 109/L. Platelet transfusion is not allowed within 3 days before testing, red blood cell transfusion is not allowed within 14 days before testing, and hematopoietic growth factor therapy is not allowed within 7 days before testing (pegylated granulocyte colony-stimulating factor \[G-CSF\] or erythropoietin \[EPO\] is within 14 days before testing). * liver function: serum TBIL ≤ 1.5×ULN (in patients with known Gilbert syndrome, TBIL ≤ 3×ULN and direct bilirubin \[DBIL\] ≤ 1.5×ULN), serum ALT/AST ≤ 2.5×ULN (for patients with confirmed liver metastases, ≤ 5.0×ULN). * Renal function: Creatinine clearance ≥ 50 mL/min. * coagulation function, defined as (including during anticoagulant therapy): prothrombin time (PT)\<1.5 × ULN, activated partial thromboplastin time (APTT)\<1.5 × ULN. If the subject is receiving anticoagulant therapy, they must receive a stable dose of anticoagulant at least one month prior to the first study administration. * 7\. For cohort 2 of phase II: According to the surgeon's assessment, the total lung function can tolerate the planned pulmonary resection surgery. * 8\. Female patients must use effective contraceptive measures during the study and for 90 days after the end of study treatment, and must not breastfeed.Female patients with reproductive potential must have a negative serum pregnancy test within 7 days prior to the first dose. Exclusion Criteria: * 1\. Participated in other therapeutic clinical trials within 28 days prior to the first dose。 * 2\. Patients underwent major organ surgery within 4 weeks prior to the first dose.or is expected to undergo major surgery during the study. * 3\. Have received lung field or whole-brain radiotherapy within 28 days before the first study drug administration, or has received palliative local radiotherapy within 14 days before the first dose。 * 4\. Patients received antitumour traditional Chinese medicine within 1 weeks prior to the first dose，and received local anti-tumor drug therapy (such as thoracic or abdominal perfusion, etc.) within 14 days or within 5 half-lives (whichever is shorter)。 * 5\. Patients with malignancies other than tumors treated in this study (except: malignancies that are cured and have not recurred within 3 years prior to study entry; completely resected basal cell and squamous cell skin cancer; completely resected carcinoma in situ of any type). * 6\. Adverse effects of previous anti-tumor therapy have not recovered to CTCAE 5.0 grade rating of ≤ grade 1 (except for toxicity judged by the investigator be of no safety risk, such as alopecia, skin pigmentation, etc.) * 7\. Have received systemic administration of potent inhibitors/inducers of CYP3A4 within 7 days prior to the first dose of treatment/randomization or are expected to receive systemic administration of these drugs during study treatment. * 8\. Patients have symptomatic central nervous system (CNS) metastases, meningeal metastases, or a primary CNS tumor that is associated with progressive neurological symptoms. * 9\. Patients have a history of severe cardiovascular disease, including but not limited to: * Mean QT interval corrected using Fridericia's formula (QTcF) from three times\> 480ms at rest. * New York Heart Association (NYHA) ≥ class II heart failure or left ventricular ejection fraction (LVEF) \< 50%. * 10\. Hypertension remains uncontrolled（systolic blood pressure ≥160 mmHg or diastolic blood pressure ≥100 mmHg ） after aggressive antihypertensive therapy. * 11\.
