Why did Xiao Wu block the door with his feet?

In the movie "Door Lock", Xiao Wu blocked the door with his feet because the director wanted him to confuse the audience and make them think that Xiao Wu was a pervert.

So the director asked Xiao Wu several times to stop Fang Hui from closing the door with his feet, or to use some five senses, or to follow the hostess to increase the audience's suspicion.

However, the director cut this line of Xiao Wu into pieces, and his appearance did not make the plot more complete, but made the audience confused.

Security guard Xiao Wu is a world full of malice, warmth and light:

Xiao Wu is a property security guard in a rented community in Fang Hui. When he appeared, he was black and blue, his eyes were stubborn, and he really didn't look like a good man.

In addition, in the film, Xiao Wu often observes Fang Hui silently, and puts his foot on Fang Hui's door twice when patrolling to prevent Fang Hui from closing the door smoothly. This once made people suspect that Xiao Wu was such a perverted man who sneaked into Fang Hui's room. After all, he knows that Fang Hui lives alone, and Fang Hui's house number and monitoring at the door have long been broken, so he is the most suspected.

It was not until the end of the film that Xiao Wu, who seems to be the most suspected, was the only source of kindness and warmth around Fang Hui.
