@timrider: "Save elevator/qi che power with roof based building2building ziplines! Super quick commute & likely reduced death defiance!" Sure it's not the most practical, but it's a fun thought and it caused us to have a good laugh. If there's anything we WOULD love to do to save the environment, it'd be to act like an urban Tarzan. @timrider wins a night at URBN, China's only eco-friendly hotel, located in the heart of Jing'an. The runner ups: @leirda with "mass broadcast of Captain Planet on public transport TVs to begin the recruitment of 1.3 billion planeteers. Go Planet!" (We loved Captain Planet as kids) and @cedric_c with "Save tons of CO2/month forbidding all media besides Shanghaiist. Less CO2, Greener city, only 1 media to spend green $ for ads." (because we're flattered). more ›

Ctrip is holding another tweet contest and they've invited us to be guest judges once again. This time around, the winning tweeter gets a night in the penthouse room of URBN Hotels Shanghai. URBN, located in Jing An, is China's first carbon-neutral hotel and uses green materials and technology to make your stay as environmentally friendly as possible. Just tweet Ctrip (remember to add the @ctripenglish) with the most creative way to make Shanghai's environment a little better. We'll announce the winners next Monday. Happy tweeting and an extra hurrah for minimizing the impact your love of luxury has on the environment! more ›

...@samgaskin, for his hilarious (and kind of sexy!) tweet: "I’d buy Natalie Portman 2 tattoos. On her left thigh RITZ & her right CARLTON but I’d use retroactive ink so they’re in Closer" as an answer to Ctrip's question: If we gave you 1,000 RMB to spend, what would you do to show the world your appreciation to the Ritz Carlton for your amazing free stay? We knew that movie was good for something! Congrats, and enjoy your free weekend stay at the Portman Ritz Carlton's sweet Club Executive Suite (worth around 15,000RMB). And thank you Ctrip! more ›
