The students of Hangzhou Wahaha Primary School received an unexpected gift on the first day of the new semester.

At 8:20, the teachers greeted every student entering the school. Suddenly, a melodious cello played the familiar melody of "My Motherland and Me", which attracted everyone's attention.

With the crisp and sweet bamboo flute sound, the two lead singers, Lu Rui and Xiao Jiayi, walked out of the crowd, and the song echoed over the square.　　

Under the influence of teachers, parents and student representatives, more than 600 students sang together, and a flash mob activity ignited the enthusiasm of the whole school.
