What are the obvious goofs in Journey to the West?

Those stupid shots in the journey to the west in' 86.

1. In the 22nd episode of The Journey to the West, the white-haired mouse becomes a weak woman and is tied to a tree. Tang Priest went to save her, but the Monkey King stopped him. So he went on, but when the Tang priest heard the cry for help again, he couldn't stand it. When he went to save him, everyone found that the tree had grown thicker! Please look at the picture below.

2. What's the difference between the nine-toothed harrow used by Bajie in the first 10 episode of Journey to the West and the nine-toothed harrow in the first 12 episode? Look at the picture below, which shows the nine-toothed harrows used by Bajie in the first 10 episode and the second 12 episode respectively. See any difference?

3. In Journey to the West episode 17, Tang Priest and his disciples crossed the flaming mountain, and Wukong borrowed a banana fan from Princess Tiefan to turn off the fire, but Princess Tiefan refused. Wukong drank tea from Princess Iron Fan and entered her stomach. Have you noticed the change before and after the teapot on the table?

4 Journey to the West 1 episode, the Monkey King, who just debuted, eats noodles in a noodle restaurant. When I first entered the noodle restaurant, there were tables and stools at the lower right of the camera. When Xiao Er brought the noodles, the table disappeared after the efforts of his front and back feet. If it's a lens, there should be a stool, which is a bit unreasonable.
