I have always loved the song "Hey Jude" since high school, it is meaningful song for me. Coincidently, I saw the first photo online, the memories of this song came to my mind all of sudden. Many people left their comments under the song on a Chinese music software. After reading their stories, I marvelled at this song. And this interesting flowchart of the song is printed on the T-shirts on online shops in Taobao. (The second photo is the T-shirt) I am seriously thinking of buying the T-shirt.😂
