Why is the word "Cheng" in Mazda Star City also called him (chí)?

The pronunciation of "Cheng" in Xingcheng is indeed (chěng.

), the reason why some people pronounce it as (chí) is because I don't usually have any word combinations. The most common combination word is galloping, and the pronunciation of "Xing Chi" is much smoother than that of "Star City". . . I've also heard of the "star pin". . . The name is not considered. . . . . . Personal opinion, that's all.
