DiDi（滴滴出行）のアプリが中国語しか表示されないのはなぜですか？
Last updated:
⚠️ SYMPTOM
中国でDiDiをダウンロードしたところ、インターフェース全体が簡体字中国語のみで、設定に英語の切り替えオプションが見当たりません。
🔍 MOST LIKELY CAUSE
DiDiの中国版メインアプリには英語のUIがありません。英語版の「DiDi Rider」アプリは別の国際向けビルドであり、対応地域以外では地理的に制限されています。
✓ HOW TO FIX
AlipayまたはWeChat内のDiDiミニプログラムを利用してください（英語UIで海外発行のクレジットカードに対応）。もしくはAmap（高德地図）やBaidu Mapsをインストールすれば、英語のDiDi予約機能が組み込まれています。
