There are two words written on the packaging of materials donated by Japan to Wuhan: mountains and rivers are exotic, and the wind and the moon are the same. It means that although mountains and rivers have their own boundaries and belong to different countries, there is no boundary between romance and moon, and people live under the same blue sky. Today, we saw these eight words on the cartons of donated materials. People who know this history, their thoughts immediately flew over the Millennium and crossed into the prosperous time of the Tang Dynasty.
