Chen (chen two voices) this surname is not much, but it should be a lot, this surname is my mother's surname, a big local surname, my grandmother is also this surname,

Chen Long
My grandmother also has this surname, and when I was young, I wondered if I should marry a person with the surname Chen, but as I grew up, I knew, no. The first time I contacted the hundred family names, I was excited to find the location of this surname, but unfortunately I did not find it, I was thinking, why not enter the hundred family names, why can it exist? I know a truth, it is better to believe in books than to have no books.
On our side, this surname is pronounced (shen four sounds), so I want to tell everyone I know, how to pronounce this word, but why can't I use this pinyin to type, if there are surname researchers, I would like to ask face to face, why is there a surname with such a big difference in pronunciation, is there too few people with this surname, or people in different places have different pronunciations?
My mother did not read (chen two) but read (shen four), we all read (shen four), I thought it was a rare surname, in fact, there are many celebrities, there are famous badminton players, there are famous screenwriters, every time I see people with this surname in different channels, I am very happy, because rare surnames need to be famous.
