Can I access the Yuelai Exhibition & Convention City, Liangjiang New Area with public transport from Jiaochangkou station, CHongqing?

The subway to reach there has not been accomplished. I suggest you walk from Jiachangkou Station to CQ Hotel bus stop to take bus no. 502 to Yutong Station, where transfer to bus no. 537 to Zhangjieqiao Station. At this station, bus no. 572 can take you to Exhibition & Convention Center South (Bolan Zhongxin Nanzhan )bus stop. Upon your arrival, you can walk to Yuelai Exhibition& Convention.
