When did Pig Bajie ask Guanyin Bodhisattva for help?

The twenty-third journey to the west: Sanzang never forgets his roots, and the four saints try Zen.

One day after crossing the Liusha River, the four of them passed by a farmhouse and asked to stay there for one night. This family has three daughters, and the hostess intends to recruit them as sons-in-law, so she persuaded them to leave them alone.

Only Pig Bajie was ready to move, and everyone else had a rest at night. Pig Bajie went to the hostess to call her mother-in-law, but in the end she was teased by her three daughters and tied to a tree for a night.

I didn't know until early the next morning that several bodhisattvas were testing them. Only Pig Bajie failed the test and needs to be corrected.
