Guitar score: Should Liang Zhu do this?

You can't see the black spots clearly without looking sideways. If it is a triangular arrow, it means that you can pluck the string quickly (plucking fast, but feeling slower than plucking the string), and sweep it in the order of four strings, three strings and one string. According to the requirements of the figure, you can't sweep two strings, so you can pluck with your fingers, not plucking the strings, but slightly approaching the plucking speed.

Personal opinion, for reference only, I hope I can help you.
