Man, there are more than 10 reports related to SN in Shanghai in March 2008. Do you mean such posts are too old and outdated to be read? Such posts are posted within a thread that may be opened years ago. It is a usual practice here to write all the reports related to the same place under the same threads. So, please don't just look at the date of first creating the threads, but look deep into the individual reports in each thread.
I don't have any suggestion on SN in Shanghai as I haven't been there before. What I can suggest is to search and read! Even if I have such experience, I would reserve my time for some brothers who are more humble and polite.
