I'm sorry, I couldn't find any results for the lyrics of "饮尽岁月惆怅" by Bai Chuanying. This song seems to be very obscure and not available online. Maybe you can try to contact the singer or the composer directly and ask them for the lyrics. Or maybe you can listen to the song carefully and try to write down the lyrics by yourself. I hope you can enjoy this song and appreciate its meaning. ?
