Legal analysis: The Code for the Quality of Railway Passenger Transport Service stipulates that the "Catering Management" clearly stipulates that the high-speed rail should be supplied with a variety of travel food and beverages, such as prepackaged drinking water and box lunch at high, medium and low prices, and prepackaged drinking water and 15 yuan box lunch in 2 yuan are continuously supplied. However, this regulation will no longer be implemented since October 1, 2117. The 15 yuan package can be sold on the train or not, and the 15 yuan package will be sold out, and there will be no replenishment on the way.

Legal basis: Article 5 of the Code for Quality of Railway Passenger Transport Service should supply various kinds of travel drinks and foods, such as prepackaged drinking water and box lunch at high, medium and low prices, and prepackaged drinking water and 15 yuan box lunch in 2 yuan are continuously supplied.
