Since Auntie wouldn't turn off the video chat, Ma Lin continued teaching.
At first, he simply tried not to let himself become irritated, and later he tried to soothe Auntie's mood so she could calm down and start trying.
The disciple training method itself especially requires patience, and her habit of constantly cursing and complaining clearly wouldn't work.
However, he shouldn't jump to conclusions too soon. It was still better to try.
The more Auntie cursed him, the friendlier he became. Mainly because Auntie thought the basic exercises were too difficult, and she couldn't learn them. Her character was such that if she couldn't learn something, she felt it was embarrassing, and then she wanted to curse innocent people, and Ma Lin ended up the victim.
