Science-themed subway debuts in Chengdu

A science-oriented promotional campaign has been launched on Metro Line 1 in Sichuan's provincial capital, Chengdu, March 11, 2019. Dubbed "Why," the campaign is designed to foster more interest in sciences. It's divided into six themes: Aerospace, disaster and protection, ocean and the environment, flora and fauna in Sichuan, life, architecture and traffic design. Elements of each theme are portrayed in the passenger carriages. "Why" is due to remain on Line 1 in Chengdu for one month. [Photo:IC]
