Well, Yi is famous, but it is not because he is heavily sponsored by government, it is because he was from "that years" and can still play accordion on the stage (or in another word, he is still young and still has energy to play in different places, this is extremely important). I know some other Chinese accordionists, they have more titles and higher reputation than Yi's from gov, they are also senior than him, but they are not active these 10-20 years due to the age, and it is hardly to find their news
