from Chongqing yuzhong district to Ciqikou & Chongqing Huayan Tourism Scenic Spot

From your hotel, you can walk to reach Eling Station where you can take the locao subway line 1 to reach Ciqikou Station directly. The subway fare is 4RMB.
To reach Huayan, you can walk to reach Eling Bus Station to take bus 268 to reach Huayan Road Station. Get off the bus, you can walk to reach that attraction easily. The bus takes around an hour and a half on the way. The bus fare is 2RMB.

Thanks Jelin.
Other problem is how to get to local zoo [i'd searched it's located at Jiulongpo disctrict] from my hotel at yuzhong district.
Can I take subway?

TQ

Yes, you can take the subway.
From Eling Station, you can take the subway line 1 to reach Daping Station where you can change to subway line 2 to reach Zoo Station. Get out of the station, you can easily see the zoo.
