Zhang issued an apology, stating: "Today, I deeply apologize for my past ignorance, my shame and especially my previous improper behaviour. I attended a friend’s wedding in Japan. It is my mistake for the oversight of [not knowing] the historical background behind the wedding venue and the political background of the other wedding guests. When I used to travel everywhere, I liked to casually take pictures. Due to the lack of understanding for the local architecture and the history and being careless about the content when taking pictures, when I took the pictures, it resulted in content that seriously harmed the feelings of compatriots. I also solemnly apologize here, I am sorry."
