What's the music for more than 8 minutes? When Xiao Ying and his grandfather were walking together, it was like playing with a flute!

I feel a little sweaty after listening to it. This should be bgm from Natsume's friend account, and its name is ゆるやかな畦で. In fact, many bgm in Natsume are very pleasant to listen to, O(∩_∩)O

PS: I think the Mandarin version is a little pitted, which is probably pirated. Many background music is not authentic and the atmosphere is not very suitable, so I suggest going to see the Japanese version personally, with better picture quality and dubbing.
