Hello, I can give you an answer according to my own experience. I have done activities on several platforms, but the most comfortable and worry-free thing is to take charge of the world by myself. That's Beijing Yundingfeng Network Technology Co., Ltd. They won't give you the price. After they give you the venue, they will leave you alone, but will implement it for you. They will not only have a world-standard conference venue, but also provide various special venues to give you different elements. Will have a different experience.
