听力原文： Please allow me to cordially welcome you to the 5th International Showcase of Traditional Asian Artwork. We have talented artists from all over Asia throughout the week. Today, we are lucky to have Tae Hoon Shim, Yuko Yoshida, and Lijian Tseng join us at this great exhibit for the first time. Before we start the exhibit, we kindly ask that all cellular phones and any other electronic devices be turned off while attending the show in respect of the other patrons also attending today's showcase. Immediately following the exhibition tonight, there will be a time of gathering to get to know the artists more intimately. Therefore, if possible, please join us after the show in the reception hall, which is located on the basement floor of the Arts Center. What does the speaker ask the listeners to do?
