黄峥致拼多多股东信：新的世界正在到来新的物种必然出现(8)

When this tiny virus was dropped into our world， it acted just like a catalyst in a test tube， accelerating the formation of a whole new world． Inevitably， some dimensions of the previous world are being restructured， some rules are being rewritten． The impact of this sweeping force will fundamentally and permanently change the world we are in now． Just like what I explained in the previous shareholder letters about PDD’s formation， new models are bound to emerge and grow in a whole new setup． We are indeed seeing the phasing out of some as new ones emerge． It is the time of reestablishment．

Human beings have long used reason to try to understand and control the world． In many cases， we succeeded， for example， science． In science， we strive to detach ourselves from the physical world we are in， to watch it as if we are a higher being “objectively” observing， understanding， and defining the world into a finite number of equations． In this framework， time is a reversible parameter in the equation -t = （-）t． It is merely a parameter in an equation to describe a predetermined trajectory of an object．
