The last time I saw Da Ruan in Brussels, Belgium attending a Fuzzy Conference several years ago. While we were focusing in an interesting conversation about the conference organizing activities of the Fuzzy Business during its infancy and formation period, Da was interrupted by an emergency that three graduate students were mugged by some petty thieves who have had robbed the Chinese students using soft weapon of shaving creams. Not only the students no longer had their passports under their procession, all their cash for the trip were completely gone as soon as they walked out the Brussels train station. This incident immediately promoted Da into a crisis management urgent care mode. After several hours of back and forth between the police, the Embassy, and the students, apparently first time making an oversea trip, was finally settled to attend the International Fuzzy Conference.
