One guess is that Zhao was pregnant when she got married, and they got married in the name of their children. At this stage, if a wedding banquet is held with great fanfare, people may see signs of pregnancy. So in order to put an end to it, they chose to postpone the wedding, but it is unknown whether it will be reissued later. Let's just say that this is a decision made by both parties.
Another guess is that he and Zhao were really busy at that time. Both of them are big names in film and television, especially Zhao, who has always been a model worker in the entertainment circle. They all share love in their hearts and don't care much about the sense of form and ceremony. Therefore, because of various circumstances, they decided not to have a wedding, and it was the most important thing to go home and have a baby after getting the certificate, so this was their choice.
I think that no matter what reason Zhao He didn't hold the wedding, I believe that they must really love each other when they chose to get married. We should all express our blessings for this, instead of taking the private life of the star as the focus of public opinion after dinner. I guess they didn't hold the wedding because they didn't have time or were pregnant. Maybe one day they will make up for this important ceremony.
