pinatl: This cache has apparently disappeared (the last five geocachers who looked for it didn't find it), and I will have no opportunity to travel to Shanghai in the near future to replace it (I currently live in France). I tried to find somebody to adopt it, but I didn't succeed, and therefore I archive the cache, and I'll probably place another one in Longhua Martyrs' Cemetery next time I visit this park, as it is a very nice place.
Anyway, this cache had a long life as it was initially placed in February 2007, exactly 15 years ago...
