Daxing... I suggest you go to the Vocal Music Department of the Central Conservatory of Music and find a senior student to teach you (I heard the standard price is 500 per lesson in Beijing, it will be much cheaper if you find a student). After all, you can get it None of the conservatory students are good. The Central Academy is on Baojia Street (the second ring road if I remember correctly). It is nearby the Changchun Street subway station, which is not far from the school.
