+# This script helps you get duplicated release notes in English after duplicated release notes in Chinese are ready.
+# Before running this script, you need to first copy the duplicated release notes in Chinese to your target English release note file. Then this script can replace Chinese duplicated release notes with the corresponding English translation according to the release and issue number information of the duplicated release notes.
