"What's wrong?" Hearing Dong Xuan's words, Chen Kan didn't say anything, Yun Gu asked first, hearing Dong Xuan's words with her hearing, naturally it was not a problem, during this period of getting along, Yun Gu really regarded Dong Xuan as her sister, maybe it could be said that Dong Xuan was regarded as a stand-in for her sister Xiaoqing on the plane of Detective Di Renjie.

"Are you in trouble?" Chen Kan raised his eyebrows and asked, could anyone find trouble with Dong Xuan?

Because of Yun Gu, the cruise ship has modified some things related to Yun Gu and Chen Kan in the real world, otherwise it will be exposed, including the issue of Chen Kan and Yun Gu's military identity, Dong Xuan can naturally get some shelter, although it is not as good as those direct military children, but it is not at the mercy of others.

"Brother-in-law, it's like this, I'm participating in a show right now, and there's a topic I'm not sure about, brother-in-law help me take a look." Dong Xuan didn't notice anything wrong with her previous words, and she didn't hear Yun Gu's words, and said, It is estimated that there is a time limit for the call, so the speed of speech is faster.

"Oh." Chen Kan and Yun Gu glanced at each other and couldn't help laughing: "What's the problem, you can say it." ”

"That's right, this is a history question, the question is what is the longest used era name in Chinese history? It offers four options to choose from, A is ......"

"Wait, this question is problematic, it's wrong." Chen Kan interrupted Yun Gu with a smile and said.

"Ahh Dong Xuan was stunned, do you want to come so unconventionally, this option hasn't been finished yet, and there is a question directly about it, is this a slap in the face?

"I dare to guarantee that among the answers, there should be Chongzhen and Kangxi." Chen Kan said with great certainty.

"Yes, indeed, is it one of the two?" Although Dong Xuan was a little surprised, she still did not forget that there was a time limit.

At this time, Yun Gu raised her hand and sucked out a ball of water from Chen Kan's tea-making kettle, and then wiped it in the air, and the water mass spread out in the air to form a mirror made of water.

The Art of the Mirror.

Dong Xuan's figure appeared in the water mirror, and then the camera kept zooming out, and Dong Xuan and the situation around her could be seen clearly.

This should be a star answering program, not only Dong Xuan, Chen Kan also saw two other acquaintances, Wu Jing and his wife, they should have participated in the promotion of the movie, the post-production work of "Wolf Warrior 2" has been completed, and the release time is scheduled at the end of this month, so during this time, Wu Jing began various publicity.

"There is a problem with this question, in Chinese history, it has been used for the longest time, whether this is the longest time in China, or the longest time of use for the question sign."

"Does it make a difference?"

"Of course." Chen Kan also had a bad taste, and said seriously: "This difference is big." ”

"In the territory, the longest time in use, as far as Kangxi and Chongzhen are concerned, it is naturally Kangxi, Kangxi reigned for sixty-one years, and the era name was naturally used for sixty-one years."

"Well, and then what?" At this moment, it can be seen through the mirror that the people on the scene, at least the host, have forgotten the question of time and have begun to listen carefully.

"But the era name Chongzhen has been used for a longer time, although Emperor Chongzhen has only reigned for seventeen years, but in North Korea, this era name has been used, if according to the records in the history books, it has been used for at least two hundred and sixty-five years."

"Then the answer is Chongzhen?" Dong Xuan said that the reason why she said this was because the host or director gave an order, and this answer is indeed what the program team thinks.

"Still not right." Chen Kan said with a wicked taste.

"Ah, no, what's that?"

"After the fall of the Ming Dynasty, North Korea still misses the old master of the Ming Dynasty, and even took the restoration of the Ming Dynasty as its own responsibility for a period of time, advocating the Northern Expedition, but later because of the gap in national strength between the two sides, it had to be stopped, and North Korea also became a vassal state of the Qing Dynasty and joined the tributary trade system of the Qing Dynasty."

Chen Kan's small class started, looking at the embarrassed people in the mirror, Chen Kan didn't plan to stop, and he didn't give the other party a chance to interject at all and continued:

"Since the Qing Dynasty has been supported as a vassal state, the era name has become a very sensitive issue, so in the national letter to the Qing Dynasty, North Korea still uses the Qing Dynasty's era name, and only in private does it use the Chongzhen era name, so how do you calculate this, for the Qing Dynasty, people don't use Chongzhen anymore, for example, I write a book now, and use Hongwu's era name directly at the end of the book, so do you say that Hongwu is the longest?"

"Then, otherwise choose Kangxi?" Dong Xuan is already confused at the moment, in fact, the staff of the program team who came up with the question is also confused, it is a simple historical topic, do you want to do this?

"That's not right, Kangxi is definitely a wrong answer." Chen Kan once again denied this answer.

"Huh? So what to choose? ”

"In China, Kangxi is definitely not the longest era name used, if the person who asked the question does not think about it comprehensively, then an option will definitely be missed, but if so, your answer to this question will come out."

"What is it?"

"Do you know that this year 2017 is also known as the 107th year of the Republic of China? This time is longer than Kangxi. Chen Kan said with a smile.

"Forehead ......"

This is embarrassing, directly to the political issue, you say that "Republic of China" is not the longest used era name in China.

Of course it is, if not, what does it mean, isn't it China?

"So, to sum up, if the option of 'Republic of China' is not provided, then you choose Chongzhen, it must be right, because the longest in the country is missing, of course, if there is, then let the questioner re-write the question and write the question clearly."

Through the technique of Xuanjing, Chen Kan clearly knew that there was no such option.

“……”

"Poof!" Yun Gu was already laughing on the side, Chen Kan did it on purpose.

"Yes, Wu Jing, you are also at the scene, I heard your voice?" Chen Kan said suddenly.

"Ah, it's Teacher Chen!" Wu Jing was stunned for a moment, and then came back to his senses, he just felt that the voice was familiar before, but he didn't expect it to be Chen Kan, he didn't know the relationship between Chen Kan and Dong Xuan, Chen Kan and Yun Gu didn't know Wu Jing when they "got married".

"Sure enough, it's you, it seems that my ears are still very easy to use, and your movie is about to be released, here I wish you a box office success of "Wolf Warrior 2" in advance." Chen Kan said.

"Thank you, thank you, Mr. Chen." Wu Jing said.
