Looks like a lot of work for you
May be you can put all the events in an Excel-Sheet so we can fill the participants .... or i will do it for the chinese delegation and send it to you ?!?!?!
Because as Brock said, otherwise my list will be very long.
In my search for Chinese participants, I have encountered several OTL problems .... Chinese Civil War (1927-1936 &1946-1950); disput between PRC (People Republic of China) and Taiwan about the legitimacy, which country is the "representative" of China, so PRC boycotted the olympic games till 1984.
So i will make a mixture .... using otl athlets and "fictive" athlets. Hope that will be okay.
