"Listen to me, thank you, because you warm the four seasons; thank you, thank you, the world is more beautiful..." with the sound of music, a child stood in front of the medical staff at the nucleic acid detection point and performed a sign language song emotionally, expressing warm gratitude and respect. Recently, similar videos have become popular on major short video platforms. Nowadays, affected by the multi-point spread of the domestic epidemic, nucleic acid testing has become normalized, and many medical staff have spared no effort to stick to the front line. In early spring, the spring is cold and chilly, and the medical staff braved the wind and rain and paid silently in the front line of nucleic acid detection to ensure that no one should be missed. These "cute babies" expressed their gratitude to the medical staff with childlike sign language dance and bow. For children, this is a new Thanksgiving education class. For medical staff, this is a driving force to fight. As a medical worker said, "even children know that we are guarding them. No matter how hard it is, it is worth it". However, I don't know when, the appreciation dance for medical staff gradually changed and evolved into the "traffic password" of their children's talent show and video account. In order to release the video of their children dancing thank-you dance on the Internet, parents have followed suit to shoot videos, regardless of the risk of their children taking off their masks and dancing, the hard work of medical staff all day, and the anxiety of others waiting in line for testing behind them. At the same time, many adults have recorded videos of dancing with the trend, and some even jumped out of accidents due to excessive force. Gratitude is not a unilateral intention, but a two-way interaction between the speaker and the receiver. If dancing thank-you dance becomes an excuse for "handing in homework", "online Red punch in", "epidemic standard configuration", "playing stem" and "rubbing heat", even if it is a good intention, it will be counterproductive. This will not only make the medical staff exhausted and at a loss, but also delay the nucleic acid testing work and affect the overall situation of epidemic prevention and control. In the context of the current multi-point spread of the epidemic, nucleic acid detection and epidemic protection are the core work. Thank you to thank, we should pay more attention to ways and methods, more true feelings and less formalism. Children dance to express their gratitude to the medical staff, which is an expression of love and a manifestation of positive energy, but there is not only one way to thank. When dancing thank-you dance has become a trend, parents should teach their children that it is better to give them more understanding and respect than dancing at the nucleic acid detection point, which interferes with the normal work of medical staff. Thank you, regardless of size, can be simply saying "thank you" or cooperating in testing. As long as we are sincere and pay sincere understanding and real respect to the efforts of medical staff, that is the most beautiful expression of gratitude. (Xinhua News Agency)
