Helvetica Neue LT Com CN is the custom system font used by Apple in China from 2010–2015, combining Helvetica Neue Latin characters with the specifically matched Lan Ting Hei Chinese characters for visual harmony on iOS devices.
In the mid-2000s, Apple began using Helvetica Neue as the system font for iOS. When Apple entered the Chinese market in earnest, they faced a problem: Helvetica Neue had no Chinese characters. A Latin font paired with a generic Chinese system font looked inconsistent. The solution was not to draw Chinese characters in a Helvetica style (that would be a massive, separate project). Instead, "CN" means the Latin letters from Helvetica Neue LT Com were paired with a specifically chosen Chinese typeface. helvetica neue lt com cn
