Slogan of subway construction

Chengdu subway, which is closely related to everyone in Chengdu, comes down in one continuous line, inherits your past and progress, and carries your joys and sorrows and life. As a commercial company, it must reflect more speed, service and quality. I don't want to know more, just like a sentence I saw on Chengdu clothing brand Mattel, which sounds good, but it is analytical.
