The exhibition I went to a exhibition with my friend yesterday, Which was about dentistry equipments and materials. The location was about 400 kilometers far. Because we had to enter the site by 8:30 am, so we set off before dawn. We arrived before the exhibition starting, so we went to breakfast, then drove back to the parking in front the site, and then we took a nap to wait the exhibition opening. We entered the exhibition when it beginning. Because my friend is a dentistry equipments and materials dealer, so our first step was to say hi with every firms he know, and chatted for a while. Later, there were some dentists comeing to visit. We have chatted to them too. What we talking was more about business, no matter the firms or the dentists. While about midday, we left then, and we drove back home. Because it was too lack of rest, so I was pretty tired.
