Bài is a very common Vietnamese noun with several related meanings, depending on context. It can mean:
- lesson
- exercise
- article
- piece/item of content
- sometimes even song or poem in other contexts
So in Bài thứ hai ở đây, bài is probably something like lesson or exercise, depending on what the learner is looking at.
In Vietnamese, hai means two, while thứ hai means second.
