I don't know. I used to watch the' Dialogue' program and invited a foreigner to claim that he could sell ice to Eskimos, marketing guru.

In one session, guest entrepreneurs describe their products and ask foreigners to give their ideas. Some of their answers are wonderful, while others are very general.

Related to this topic, a boss of health wine said that our product is health wine. Before he finished, the foreigner said directly, nonono, I can't make people believe that alcoholic things are good for their health.
