Synonyms are trouble.
I went to the Beijing Tourism Bureau website today and a most colorful flash banner urged me to do a rather strange thing: "Contact the Olympics".
I don't know how long this banner is online already and I wonder how long it will take them to realize they should take if offline pretty soon again. Why do so?
The problem is ti3yan4 体验 and gan3shou4 感受 mean basically the same thing: to feel or experience with (in my understanding!) 体验 having a stronger emphasis on physical experience. All in all it is definitely not about writing an email to Jacques Rogge.
Suggestion: Break it down - "Experience Beijing and the Olympics", maybe even: "Experience Beijing and feel the Olympics". Native speakers anyone?
