Q: Do you think the concept of space network, WEB 3.0, metaverse, and digital twin is the future direction? If yes, where is the best place to start?

A: I think it is necessary to have a mapping relationship between the virtual world and the real world. Does this mapping need to be exactly one-to-one? It is not clear yet. As for the article questioning the metaverse, one point is that if the experience of the metaverse is copied to the real experience, it will only hinder the evolution of new technologies.

At present, the number of visitors in the virtual world is far less than in the real world. Cryptocurrency, as an important pillar of the virtual world, has recently become a bit ridiculous because of the bloodbath.

我目前能想到的是，如何利用虚拟世界作为创作者的非物理接触的创作媒介，以及创作效果的评估媒介，以创作的结果来反哺真实世界。

What I think about is: How to use the virtual world as a creative medium for creators without physical contact, as well as the evaluation medium of creative effect, the real world is fed back with the results of creation.

比如，货架的3D模型是与真实货架一一对应的，我们可以理解成一种数字孪生，货架规划/设计者通过虚拟空间提供的工具，根据美感/营销/广告的需要，在虚拟空间中设计货架陈列，并通过AI工具或者虚拟世界中的测试员，对其进行验证，结果理想后则可以实施到真实货架上。

For example, the 3D model of the shelf is in one-to-one correspondence with the real shelf. We can understand it as a digital twin.

Shelf planner/designer designs shelf displays in virtual space according to the needs of aesthetics/marketing/advertising through the tools provided by virtual space, according to the needs of aesthetics/marketing/advertising.

And through AI tools or testers in the virtual world, it is verified, and after the results are ideal, it can be implemented on the real shelf.

于是问题就可以简化为几个交由技术实施的步骤了，比如，需生成和真实货架一样的3D模型，需有商品的3D模型库，需有无代码或低代码或由数据生成货架陈列的工具，需要一个测试/体验的标准，等等。

So the problem can be reduced to a few steps handed over to the technical implementation.

For example, it is necessary to generate the same 3D model as the real shelf, a 3D model library of products is required, there is a need for no-code or low-code tools for generating shelf displays from data, a test/experience standard is required, and so on.

从不浪费开发资源的角度看，先投资一个海量的商品3D模型库是最具备可进可退的特点的。

From the perspective of not wasting development resources, investing in a massive product 3D model library is the most reversible feature.
