The business district of the first-tier cities is really extraordinary, satisfying all our ideas about Huaqiangbei. The last time I came to Shenzhen was mainly to participate in the exhibition. I only knew that there was a Shenzhen Convention and Exhibition Center. I didn't expect to come to the Shenzhen International Convention and Exhibition Center again. This Shenzhen International Convention and Exhibition Center seems to be a bit bigger, because it is a new exhibition hall, so the facilities are very new. The last time I came to Shenzhen was to participate in the 22nd CIOE photoelectric exhibition. The scale of the exhibition is really large, giving full play to the new pavilion and new characteristics, the exhibition area will reach 160,000 square meters, gathering more than 3,000 exhibitors. During the same period, six theme exhibitions, gathering many hot technology and products. On September 1 this year, I will come to Shenzhen to participate in the 23rd CIOE photoelectric exhibition. I don't know what unexpected surprises will be gained at this year's exhibition.
