The myth of Mrs. Wong's noodles

By the way, the story of Mrs. Wong's noodles all started here with a Sunday night programme on Chinese food - http://www.arte-tv.com/fr/connaissance-decouverte/chine/262344.html. Mrs. Wong and her husband can be found in the Night Market in Kaifeng. I wonder if we'll really find Mrs. and Mr. Wong. Will we recognize them? Jérôme probably will but I'll probably be so overwhelmed by the food to see anything (what if the Night Market turns out to be a total flop? What if the Wongs don't really exist?)
