据reddeit，旅居上海的外籍人士亲自查勘，说路牌并没有被拆。不过这不是重点。

"I just visited Urumqi M. Road to have a look at what's going on for myself...There's a photo going around showing that the street signs of Urumqi M. Road have been taken down.. that's false. All the signs are in tact down the entire length of the road. HOWEVER, there are tons of workers currently boarding up pretty much every street in the area with those blue and yellow walls we came to love during lockdown..."

当然，掩耳盗铃、掩人耳目都是不对。
