薄饼 (báo bǐng), literally ‘griddle cake’ is a pancake rather than what is normally considered ‘bread’. They certainly aren’t made in bread machines.
Note 刨冰 (bào bīng) means ‘shaved ice’, a popular summer dessert so searching Google etc for ‘bao bing’ will return more recipes for that than for flatbreads.
Just to confuse things further 抱病 (bào bìng) means ‘to be ill’ which you should try to avoid!
The only flatbread I regularly come across in China is 馕 (náng), a variation on the Middle Eastern naan. These these are baked in commercial ovens and don’t use bread machines, either. They do, however usually contain yoghurt.
