It's important to note that "most people" can be measured in two ways:
* Native Speakers: This refers to people who learned Mandarin as their first language. In this case, Mandarin Chinese has the most native speakers.
* Total Speakers: This includes native speakers as well as those who learned Mandarin as a second language. Here, Mandarin Chinese also has the most speakers, though the numbers are slightly lower than for native speakers.
However, the exact number of speakers varies depending on the source and how "speakers" are defined. Some sources might include dialects like Wu, Hakka, or Min Nan within the definition of Mandarin, while others might count them separately.
