在日常生活中,大家最见怪不怪的现象之一,就是俗称“牛皮癣”的城市小广告了。它极像人类常见病“牛皮癣”症状——不易治疗,容易复发,无法根治。痛痒不烈但极其丑陋, 所以人们把乱贴乱写的广告称为城市“牛皮癣”。 In our daily life, one of the most weird things we see is the small urban advertising commonly known as “psoriasis.” It is like a common human disease “psoriasis” symptoms - not easy to treat, easy to relapse, can not cure. Itching is not fierce but extremely ugly, so people refer to advertisements that mess up and scribble as the city “psoriasis.”
