Former South Korean girl group Girls' Generation member Jung So-yeon's participation in "Sister Riding the Wind and Waves" can be described as a stone that stirred up thousands of waves and triggered a heated discussion among many netizens.

The dregs of K-pop culture
As for the focus of the discussion, it naturally revolves around Jung So-yeon's nationality, a single American nationality or dual citizenship (US/Korean).
The reason why everyone pays so much attention to this is that everyone knows that there is a consensus on "limited Korea" in internal entertainment. Perhaps in the eyes of many people, the root cause of "limited Korea" comes from factors other than entertainment, but in fact, internal factors are the key. Today's "rice circle culture" of internal entertainment, including a series of operations such as "hitting the investment", "responding to assistance" and "brushing the list", are all derived from Korean entertainment.
Objectively speaking, Korean entertainment does have unique features, but there are also many pieces of. The "rice circle culture" is the most typical example, which has poisoned a large number of teenagers and deprived them of the ability to distinguish between right and wrong. For example, the Canadian artist Wu Mou, the crime has been revealed, and there are still fans who are not happy about it. The rhetoric is fierce and extreme, which makes the public stunned, and it cannot be said that it is not crazy.
It is worth noting that the madness of Wu's fans is not an isolated case, but a universal one. The official media criticized Cai Xukun for "singing on credit", and his fans besieged the official media, such a case can only be described in the current internal entertainment. If this unhealthy trend and evil atmosphere cannot be stopped, it will certainly cause serious troubles in the future, so in recent years the relevant departments will focus on rectifying the "rice circle."
The "game" rules of "Limited to Korea"
It can be seen from this that "limited Korea" is essentially "limited" to Hallyu culture, because Hallyu culture is basically equivalent to "rice circle culture". However, there is no "one-size-fits-all", and there is also a certain degree of "exemption", such as foreign artists working in South Korea and Korean artists who have developed in China for a long time.
Foreign artists working in South Korea include Chinese artists and artists from other countries, such as Song Yuqi, Lisa and others, who are not included in the "Korean restriction".
Korean artists who have developed in China for a long time are special cases, and the Korean actress Qiu Porcelain, who is married to Yu Xiaoguang, has not been affected by the "limited Korea".
But "exemption" should definitely not become a BUG, for those who have dual citizenship of K-pop artists, "Korean restriction" must play its due role. Based on this, whether Jeong so-yeon is a single U.S. nationality or a dual citizenship (U.S./South Korea) will involve the principle of "Korean restriction". If Zheng Xiuyan is really just an American, then no one has anything to say, this is the "game" rule. On the contrary, it is also reasonable to require program rectification and Zheng Xiuyan's withdrawal from the competition, which is also the "game" rule.
The "butterfly effect" or incurs a card BUG
Once Jeong so-yeon is confirmed to have dual citizenship (US/Korean) and acquiesced in "Sister Riding the Wind and Waves", it is very likely that the "butterfly effect" will be triggered.
PS: The butterfly effect refers to the long-term huge chain reaction of the entire system in a dynamic system, where small changes in initial conditions can be driven.
In the context of "Limited Korea", ignoring Jeong Soo-yeon's nationality may seem insignificant, but it may prompt K-pop stars to collectively card BUG. At present, more than 70 countries in the world recognize or accept dual citizenship, and K-pop stars can choose a country with a relatively low naturalization threshold in it, and then entertain and earn money as an artist in that country after joining.
The income gap between Chinese and Korean artists
Some people may question whether K-pop stars can really do this?
As Dunninger said:
"As soon as there is a proper profit, capital will be very bold. As long as there is 10% profit, it will be used everywhere; 20% will become lively; 50% will cause positive risk-taking; 100% will make people reckless of the law; 300% will make people not afraid of crime, not even the danger of hanging their heads. ”
South Korean artist Huang Zhilie once personally admitted that his appearance fee in internal entertainment is 100 times that of Korean entertainment, which is 10,000% profit. According to relevant data, according to a statistic made in 2017, only 1% of Korean artists with annual income of 1.955 billion won (10.19 million yuan), only 10% of 367 million won (1.913 million yuan) and 7 million won (36,490 yuan) accounted for 89%.
In the past two days, there happened to be an eighteen-line domestic artist "crying poor" on the Internet, saying that due to the impact of the objective environment, there was only half a year's workload a year. As a result, the income has dropped sharply, but there are more than 200,000, which is enough to beat 89% of Korean artists. The eighteen-line artists are still like this, and the income of those top stars is even more attractive, and they have already entered the level of "billion" as the unit of measurement.
epilogue
It is conceivable that if there is a chance to develop in internal entertainment, there will definitely be a large number of K-pop artists who do not mind having one more nationality. If this is the case, then the "Restriction on Korea" measures will be instantly broken, which is what we do not want to see. Therefore, Zheng Xiuyan's nationality must be clarified, and she cannot turn a blind eye to this matter and strictly implement the rules of the "game".
Personal opinion, do not like it or spray.
