The 5D holographic light and shadow banquet hall will actually cost more in the early stage, but it is still cost-effective in the long run. That's what our hotel did, and it was carefully planned at that time. In fact, we did not give up the traditional decoration, but added the new technology of 5D holography on the basis of the traditional decoration. At that time, we asked Shenzhen Times Technology to do it. We chose their home because we realized that this industry is really not the value of projectors, but the original ability and the renewal ability of film sources. They have their own R&D technology and art design team, so their works will be updated all the time. It won't be out of date, and their films are all made according to the process of my banquet, which is very suitable. Unlike other families in the market who want you to match it yourself, it may not be suitable for the actual wedding theme. They are all used now, and many customers are willing to choose this method. Moreover, our hotel also has publicity highlights, which is still of certain value.
