Hello Tien,
Yes, I mean Anicca, Dukkha and Anatta. You can choose the translation that appeals more to you, that’s not the point. I don’t wanna be rude but it will be very helpful to focus on the general idea beyond the exposition of someone else, not in the specific words. They can be interpreted in different ways by each an everyone of us.
It’s very likely that when I used the word “bird” I imagine a different species than you. You know what I mean?
Furthermore my english is not the best so I have to apologize for that.
