Which is the best exhibition company in Chongqing at present?

I wonder if it's the biggest. Let me recommend some big exhibition companies I know to the landlord.

Chongqing wode exhibition co., ltd

Chongqing huibo exhibition co., ltd

Chongqing Hua Gang Exhibition Co., Ltd.

Chongqing Zhongxin Exhibition Co., Ltd.

Chongqing lijia conference exhibition co., ltd

Chongqing International Conference and Exhibition Center

Chongqing zhonghuan exhibition planning co., ltd

Basically, every exhibition company is the owner of its own brand exhibition, so I dare not make my own judgment.
