"Since I am working on this position, I want to do my job right and be responsible for society, the company, the passengers." Many passengers know about Li Mei. Some of them even especially wait for her bus to ride. "She drives very steadily. We are still willing to take her bus even though there is no vacant seat," said some senior citizens in Chongqing.
