6:10--Cantonese have difficulty in pronoucing "R" but can pronounce "L" very well with the tongue placed at the upper jaw. I have the feeling 蕭生is trying to say that Cantonese are often promouncing "R" as "L".
Simplify Chinese is going to be a phonic language based on the speaking language. A lot of words are using similar sound but simpler word to replace it. Like the work noodle is replaced by the word face. So the meaning of the word is not there anymore. Why not totally change it to Roman translation. And writing it in 26 English letters. It will be more efficient in writing in the sense of the CCP. Then the tradition of Chinese language will be completely gone.
