At the concert in Beijing, the brand used to play his hometown acoustic guitar was Gibson, an American brand and one of the best-selling brands in the world. At the closing ceremony of the Beijing Olympic Games, the old man played this brand in London for 8 minutes, but Gibson made few acoustic guitars. If I remember correctly, the model he used should be J-200, used by Elvis Presley. Classic model. . . . . Is this the website of American station/products/acoustic-instruments/Gibson-acoustic.aspx?
