* 2.18 Years to 75 Years, Histologically or cytologically confirmed Routine treatment of patients with advanced lung cancer and triple-negative breast cancer(Including TKI treatment failure patients);
* 3.EGFR/B7H3 expression was confirmed positive in tumor site by immunohistochemical test within 3 months before signing the informed consent form;
* 4.According to RECIST version 1.1 of solid tumor efficacy evaluation criteria, there should be at least one measurable lesion during screening period (results are available within one month prior to screening period) ;

* 12.Patients with a prior or concurrent second tumor, except in the following cases:

  * Adequately treated basal cell or squamous cell carcinoma (adequate wound healing required prior to enrollment);
  * Carcinoma in situ of cervical or breast cancer with no signs of recurrence for at least 3 years prior to study after curative treatment;

## Arms

- **Treatment** (EXPERIMENTAL) — Patients will receive 2\*10e6/kgCAR-T cells.

## Interventions

- **EGFR/B7H3 CAR-T** (BIOLOGICAL) — 2 × 10\^6/kg CAR-T cells,For subjects with body weight greater than 60 kg, the number of cells can only be calculated according to 60 kg of body weight.

## Primary Outcomes

- **Safety by Common Terminology Criteria for Adverse Events (CTCAE) V5.0** _(time frame: In CAR-T cells infusion, up to 52 weeks.)_ — The type, frequency, severity, and duration of adverse events as a result of EGFR/B7H3 CAR-T cells infusion will be summarized

## Secondary Outcomes

- **Objective Response Rate (ORR)** _(time frame: In CAR-T cells infusion, up to 52 weeks.)_
