Easy transportation from Crowne Plaza Panda Garden Chengdu to the city-center

What do you mean by the city center? Is it Chunxi Road? This area can be regarded as the flourishing one in this city.
If yes, there is no direct public bus or subway that can take you to the Chunxi Road. You need to transfer.
Walk to Ertaizi Station and take public bus no.198a to South Chuanshan Overpass Station. Then transfer to bus no. 166, and get off at South Shamao Road Station. After arriving, walk to the destination directly. The ticket fare is CNY 4 per adult.

If you cannot find the bus stops easily, you are suggested to take a taxi from the hotel. The cab fare is about CNY 45.

Thank you for your prompt answer !
