Chinese netizens react to Mickey Mouse wearing Hanbok at Disneyland in the US... Why?

When Walt Disney's iconic characters Mickey Mouse and Minnie Mouse delivered New Year's greetings wearing traditional Korean clothing, some Chinese internet users expressed their displeasure.
Recently, Walt Disney Theme Park Disneyland posted on its official Instagram account that it held a Lunar New Year event at Disneyland in California, USA.
The video was released. In the video, the video greets the new year in Korean, Chinese, and Vietnamese with the phrase "Lunar New Year (Happy lunar new year)".
At the event, Mickey Mouse and Minnie Mouse appeared for the first time wearing hanbok, drawing attention. In the past, Lunar New Year was an unfamiliar concept in the West, so the Chinese Lunar New Year was celebrated as a Chinese New Year.

year," "It's Chinese New Year, not the lunar New Year," "Chinese New Year is called the lunar New Year.
