Going to WOW from Green Tea Inn, Bus or Subway?

I will be staying at the Green Tea Inn near the Shaibu Station of the Long Gang Line. If I want to go to WOW, can I ride the Long Gang Line at Shaibu, then transfer to the Luo Bao Line at the Lao Jie station to head towards Shi Jie Zhi Chuang station? Will this route take a shorter travel time than going to WoW by bus? Thanks.
