Nanjing Hexi Foreign Language School (NHFLS) and Jerry Knight STEM Academy at Wester Middle School, which is part of Mansfield Independent School District (Mansfield ISD), Texas, USA, established sister school relationship. The epidemic caused by the new coronavirus delayed the winter research activities that both sides should have carried out.

Therefore, Mansfield ISD sent a letter of condolences expressing their regret and concern for the teachers and students of the sister school. They sincerely wish that the epidemic situation will be overcome at an early date and the friendly exchange activities between the two sides will continue.
