A young man crossed the sea and went to continue his studies in a different place. There, he met a beautiful woman, who warmly offered him help and her friendship. The two ultimately ended up falling in love. This should have been a wonderful love story, but the ending wasn't the usual happily ever after. Instead, the boy was arrested for leaking state secrets, and the girl proved to be a spy who used pornography to get intelligence.

This is not a plot written by American screenwriters for Hollywood blockbusters, but a real Chinese event disclosed in a series of programs detailing cases where Chinese students studying in Taiwan were often targeted by spies who lure them with money, love, and friendship.

According to the program, over 100 espionage cases involving Taiwan have been prosecuted this year, highlighting the security challenges brought about by the infiltration of espionage in the mainland under the current cross-strait situation.

In order to obtain intelligence, spies often resort to various means of seduction. In the program, young students from the mainland are their new targets, as they are young, highly educated, and are also easily deceived in an unfamiliar environment.

Since Taiwan's current leader Tsai Ing-wen assumed power, cross-strait relations have been relatively tense, as the Taiwan authorities continue the illusory dream of Taiwan's "independence."

In recent years, the United States has also repeatedly tried to collude with the mainland's red line on the Taiwan issue. Given the context of the current Sino-US trade dispute, the tension between China and the United States has undoubtedly contributed to the more arrogant flame of "Taiwan independence forces." In their mind, this is a good opportunity to put pressure on the mainland and gain political interests for Taiwan.

However, Tsai Ing-wen may forget the fact that Taiwan is an inseparable part of China, and the general trend of cross-strait relations will not change in the future, no matter what kind of espionage she and her authorities undertake. The more activities the Taiwan authorities take on to undermine cross-strait relations, the less favorable it is for Taiwan's future.

According to a report by www.haiwainet.cn, the latest survey by Taiwanese media shows that in the past year, the proportion of people in Taiwan who are dissatisfied with Tsai Ing-wen's handling of cross-strait relations has climbed to 68 percent, which is the highest its been in the past three years.

At present, "the cross-strait relations are not good, Taiwan will not be good" has become the consensus of many people. Specifically, if cross-strait relations are not good, many ordinary people in Taiwan will be affected. Only by reducing the number of mainland passengers, Taiwan's tourism industry will suffer a lot.

Nowadays, the development of cross-strait relations has become a pain point for many industries in Taiwan. If the Taiwan authorities do not take it seriously and  refuse to recognize the "1992 Consensus" (which affirms that the Chinese mainland and Taiwan belong to one and the same China), this situation will be difficult to change.

Of course, the espionage has also given the mainland security department a warning that we should have a clear understanding of the cross-strait anti-espionage situation.
