Title: The words used to send banners in the Forbidden City are controversial.

"Regret the motherland's strength and defend Taian, Kyoto." This is a thank-you letter on the banner presented by the Palace Museum to the Beijing Public Security Bureau the day before yesterday. In just ten words, the netizen picked the wrong word: "regret" should be "defense". After responding to the media the day before yesterday that "the words on the banner are synonymous with the word" regret "in" It's easy to shake the mountain and regret the difficulty of the People's Liberation Army ",the Forbidden City said again yesterday that experts were consulted before making the banner, and the words were correct. However, linguists believe that the word "regret" is wrong.
