 <h2 class="accordion-header" id="headingTwo">
        <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#collapseTwo" aria-expanded="false" aria-controls="collapseTwo">
          杜甫

<div id="collapseTwo" class="accordion-collapse collapse" aria-labelledby="headingTwo" data-bs-parent="#accordionExample">
        <div class="accordion-body">
          杜甫（712年—770年
          ，字子美，原籍湖北襄阳，后徙河南巩县。唐代伟大的现实主义诗人，

<div class="accordion accordion-flush">
