Bobo pot is a special dish in Guangzhou. It mainly puts the ingredients in an earthenware pot. After baking at extremely high temperature, the soup in the casserole quickly evaporates and makes a sound of "Babu", which is pronounced as "Babu" in Cantonese.
Zuibao is similar to Zuibao in Cantonese, so many people will write Zuibao as Zuibao, so there is no difference between them.
