[19] Chiu repeatedly interrupted the question process by asking Chen to speak Mandarin Chinese for easier communication, or the session time cannot be lengthened to accommodate the interpretation,[20][21] but Lee's translation contained contextual errors,[20][21][19] so Chen I-hsin intervened during the heated argument and tried to introduce the existing real-time synchronized interpretation on progress at site as the solution same as the common conference practice in the other countries, but Chiu still insisted his way[20][21] Chen later apologized to the public for the good intention of practicing the national language law being turned into a linguistic communication tragedy, and condemned Chiu for "bullying" (鴨霸), but Chiu denied the allegation and claimed that a language is a tool of communication.
