2013年11月，北京地鐵官方微博發布圖文，話「蝗蟲」經過之後嘅10號線，一片狼藉，又話「北京有時候寬容過了頭，對於惡意破壞北京首都的行為，我們只想說『這裡不歡迎你！』」呢番說話引起公眾關注。
In November 2013, the official Weibo of the Beijing Metro posted a picture and text saying that Line 10 was in disarray after the "locusts" passed, but said that "Beijing is sometimes too tolerant, and we just want to say 'You are not welcome here!'" for malicious destruction of Beijing's capital.
