Is it free for 70-year-olds from other places to take public transport?

It's free. For example, 20 19, 10, 1, Panzhihua hukou and non-Panzhihua hukou, and foreign hukou come to Pankang for the elderly. After reaching the age of 70, you can take the bus with the free bus IC card or relevant valid documents handled by the Municipal Public Transport Corporation, so it is free for the 70-year-old people from other places to take the bus.
