Do any Chinese languages or dialects contain a rolled/trilled R? From 20:00 to 22:00 of this video (https://www.youtube.com/watch?v=pnMeISMY6eM), the speaker appears to pronounce the R sound with standard Mandarin pronunciation in 若 and 仍然. However, he rolls the R in 肉. He also taps his R in 人, but not as strongly. He doesn't pronounce the R at all in 而. For context, he from Malaysia and he says something in Cantonese later on in the video.
Do any native Chinese speakers of any dialect roll/trill their R's, or would this be interference from a non-Chinese language?
According to this map there are some Chinese languages in which the trill r is present.
