2014年2月20日《人民日报》刊登法学博士﹑中国社科院副研究员董文勇的文章《地铁“禁食”该不该》。该文认为,可以倡导地铁内禁食,但不宜通过立法的方式促成。董文勇认为,地铁高峰期如此大的人流量,有限的执法力量能否确保禁令的执行,是一个问题。如果有法律却得不到落实,反而会降低法律的权威性。而且,少数群体有特殊进食需求。“比如,低血糖病人如不适需随时就餐,这样的行为是否也要一并禁止?”2012 February 20, 2014 “People’s Daily” published law JD, Associate Professor of Chinese Academy of Social Sciences Dong Wenyong article “subway” fasting “should not be.” The article believes that it can promote fasting inside the MTRC, but it is not appropriate to promote it through legislation. Dong Wenyong believes that such a large flow of people in the subway peak, the limited enforcement force can ensure the implementation of the ban is a problem. If there is law but can not be implemented, it will reduce the authority of law. Moreover, minorities have special eating needs. “For example, hypoglycemia patients need to eat at any time, such behavior should also be prohibited? ” 2012
