What classic crisis public relations cases do you know?

Actress Cecilia Han is angry at Ctrip's bundling. She repeatedly found and manually canceled the "pre-selected safe" hidden under the booking information, but still "routine" failed, and there was no way to complain. At the end of this Weibo, Cecilia Han asked Ctrip to face the problem honestly, apologize to the public, and advised "Ctrip is in hand, see clearly before you go." This Weibo undoubtedly became the headline of Weibo that day, and many netizens posted their own real cases, which attracted the attention of the audience. The incident continued to ferment, and the people who ate melons were waiting for Ctrip's official statement. Finally, Ctrip responded: Cecilia Han's complaint will be handled according to the normal process, but no further explanation will be given.
