Is there a problem with mpvue displaying elements based on variables?

<template>
  <div class="ts">
    <div :class="{"show": language === "zh"}">zh</div>
    <div :class="{"show": language !== "zh"}">en</div>
  </div>
</template>

export default {
  data() {
    return {
      language: "zh"
    };
  },
  ...

.ts>div{display:none}
.ts>div.show{display:block}
The

page always displays en, first and then zh,. I have set the default value for language to zh,. Why is this happening?
