  card_weixin:
-    enable: false
+    enable: true
  card_recent_post:
    enable: true
    limit: 5 # if set 0 will show all
    sort: updated # date or updated
    sort_order: # Don't modify the setting unless you know how it works

    - const tocStyleVal = tocStyle === true || tocStyle === false ? tocStyle : theme.toc.style_simple
    if showToc && tocStyleVal
      .sticky_layout
        include ./card_post_toc.pug
    else
      !=partial('includes/widget/card_author', {}, {cache: true})
      !=partial('includes/widget/card_announcement', {}, {cache: true})

      !=partial('includes/widget/card_top_self', {}, {cache: true})
      .sticky_layout
        if showToc

        !=partial('includes/widget/card_recent_post', {}, {cache: true})
        !=partial('includes/widget/card_ad', {}, {cache: true})
  else
    //- page
    !=partial('includes/widget/card_author', {}, {cache: true})
    !=partial('includes/widget/card_announcement', {}, {cache: true})
+    !=partial('includes/widget/card_weixin', {}, {cache: true})
    !=partial('includes/widget/card_top_self', {}, {cache: true})      

    .sticky_layout
      if showToc
        include ./card_post_toc.pug

      !=partial('includes/widget/card_categories', {}, {cache: true})
      !=partial('includes/widget/card_tags', {}, {cache: true})
      !=partial('includes/widget/card_archives', {}, {cache: true})
      !=partial('includes/widget/card_webinfo', {}, {cache: true})
      !=partial('includes/widget/card_bottom_self', {}, {cache: true})

#aside-content .card-widget#card-wechat {
  background: #57bd6a;
  display: flex;
  justify-content: center;
  align-content: center;
  padding: 0;
  cursor: pointer;
  border: none;
  height: 110px;
}
#aside-content .card-widget {
  border-radius: 12px;
  transition: 0.3s;
}
#flip-wrapper {
  -webkit-perspective: 1000;
  perspective: 1000;
}

#flip-wrapper {
  position: relative;
  width: 235px;
  height: 110px;
  z-index: 1;
}
#flip-content {
  width: 100%;
  height: 100%;
  -webkit-transform-style: preserve-3d;
  transform-style: preserve-3d;
  transition: cubic-bezier(0, 0, 0, 1.29) 0.3s;
}
#aside-content #flip-wrapper #flip-content .face {
  position: absolute;
  width: 100%;
  height: 100%;
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  background: url(https://img02.anzhiy.cn/adminuploads/1/2022/09/11/631ddb7c9b250.png) center center no-repeat;
  background-size: 100%;
}

#aside-content #flip-wrapper #flip-content .back.face {
  display: block;
  -webkit-transform: rotateY(180deg);
  transform: rotateY(180deg);
  box-sizing: border-box;
  background: url(https://img02.anzhiy.cn/adminuploads/1/2022/09/11/631ddeb0900b7.png) center center no-repeat;
  background-size: 100%;
}
#flip-wrapper:hover #flip-content {
  -webkit-transform: rotateY(180deg);
  transform: rotateY(180deg);
}

将 background: url(xxx) center center no-repeat; 中的xxx换成自己的公众号图片即可，两处的正反图片可以自行尝试。
