1. The hug time is short. If you look closely, you will find that the scenes of the princess hugging are actually very short and beautiful, and the female stars are thinner. Basically, the weight of female stars is controlled at about 90 kg, and there are almost no shots of the female host running wildly, so it seems that the male protagonist is particularly relaxed.
2. Be good at using tools. For example, did you see the biography of Chu Qiao? Are there many scenes where the princess hugs? It's easy to hug Zhao in TV series, but after watching the tidbits, you really laugh and cry. What is the truth? Look at the picture below, we will find that Zhao didn't answer the phone at all. Zhao has a table under her body to support her. Do you really want to laugh when you see this? It's not that Kenny Lin can't hold it. It's normal to shoot a scene for several hours, or shoot it dozens or even hundreds of times while filming. If you don't need tools, this hug may take hours, and not everyone can stand it.
Another situation is to use body doubles, which are usually used when the male host is younger or the female host is older. It's also nice to shoot the princess on the back without showing her face.
