I stayed in Zhanggongling for about 20 days, with one company in each class. Military training in the sun, practice every day. You said you were tired, not strict and didn't practice. How do you arrange this meeting? It's basically the same. Military training is hard training, singing practice in the evening, and singing competitions. Finally, there will be a performance review ceremony, and companies will take to the rostrum to see which pair is neat as a competition.
