What is the stalk of broccoli in the epidemic?

Everyone has flowers. Dad gives you broccoli. Doctors in the First People's Hospital of Foshan City have been very busy recently, because they went to the front line of epidemic prevention and control. On the last day of his daughter's college entrance examination, he rushed to pick up his daughter Lu Xiaoyun outside the examination room as soon as he got off work. Seeing other parents holding flowers, he had a brainwave and went to the supermarket to buy a broccoli. The price of this broccoli is 3.2 1 yuan, and his daughter's birthday happens to be March 2 1, which is very meaningful.
