Shenzhen Convention and Exhibition Center is a large public building integrating exhibition, conference, business, catering, entertainment and other functions. The total construction area of the Convention and Exhibition Center is 280,000 square meters, 540 meters long, 282 meters wide from north to south, 60 meters high, six floors above ground and three floors underground. I went to an electronic exhibition from Dongguan. I took the train from Dongguan Station to Shenzhen Station and then transferred to the subway to the exhibition center. The transportation is very convenient.
