Netizens complained that the booking was rejected after writing "Taiwan, China" in the booking form. Ye Yaoyuan said: If you want to come, you will violate our country's national dignity.

Recently, some Chinese netizens posted on social media that they were asked to complete documents when applying for a tourist entry permit to Taiwan. Officials pointed out that the words "Taiwan, China" on the hotel reservation form they attached dwarfed my country's national flag, and asked them to re-upload the documents without the dwarfed words. Chinese netizens complained, "Is this necessary for travel?" Ye Yaoyuan, chair professor of international studies at the University of St. Thomas in the United States, bluntly said, does Taiwan deserve to be eaten by China? He also criticized, "You are promoting internal propaganda within the country to eliminate Taiwan's sovereignty. We have no other way to counterattack other than protesting; but if you want to come to our country, you still want to trample our country's national dignity. This is called the law of nature."

According to media reports, a Chinese netizen posted a screenshot of a supplementary copy of Taiwan's tourist entry permit on a social platform. Since the word "Taiwan, China" appeared on the hotel reservation form, the applicant was asked to provide a new reservation form with "dwarfed" text removed. The applicant was also required to write the text "Respect Taiwan as a sovereign and independent country, and the two sides of the Taiwan Strait are not affiliated with each other" and sign and date it before uploading it. The poster asked, "Is this necessary for a trip?"

In response to this, Ye Yaoyuan posted 3 comments on Facebook: First, what does "Is this necessary for traveling?" Does Taiwan deserve to be misfortune and be eaten by China? If you want to carry out internal propaganda in your territory to eliminate Taiwan's sovereignty, we have no other way to counterattack except protest; but if you want to come to our country and trample our national dignity, that is called natural justice.

Second, conversely, when Taiwanese go to China, they are often asked to use the method of "removing Taiwan sovereignty" to interact with the Chinese. "I personally believe that there is no home without a country. I don't need to kowtow to China to go to China, so I choose not to go to China at all. But other people have their own considerations (Taiwanese businessmen, etc.), and this is a personal choice. But I personally think that I am worthy of my own choice."

Third, "China has always been one of the subjects of my political science research, so my research is often affected by my speeches (I don't know how many times I have been rejected by certain journals controlled by Chinese people in the past ten years). But I will not change my political identity because of this, nor will I kowtow to China. I never think there is anything wrong with protecting my country and protecting my sovereignty, and I hope everyone will follow suit."
