Artest of Tik Tok is the grandmother of my little brother in western Yunnan. Little brother in western Yunnan is a video blogger on the short video of vibrato, and he is from Baoshan, Yunnan. In Yunnan dialect, grandpa Artest means grandparents, so Artest in the video is my brother's grandmother in western Yunnan. Although the old man is old, he has always had a childlike innocence, which is very pleasing.
