Save the Bachelor of Heaven

After April, came May.

For Lin Yang's birthday, Xiang Nan gave him a painting he made as a birthday present.

The painting shows three sheep grazing under the pine tree, implying that Sanyang is prosperous and the pines and cypresses are evergreen.

Lin Yang liked the painting very much and expressed his thanks to Xiang Nan.

In May, Xiang Nan rejected the publishing requests of several publishing houses.

However, as "Ghost Blowing the Lantern" became more and more stolen, spread more and more widely, and became more and more famous, major publishing houses became more and more interested in it.

Several publishers had obviously been rejected, but they still called repeatedly, which made Xiang Nan feel a little disturbed.

In June, the college entrance examination officially hit.

Although Xiang Nan and the others were still sophomores in high school, they already felt the tense atmosphere in the examination room where the battle was raging, the smoke filled the air, and the bayonets were red.

But fortunately, Xiang Nan has already been recommended and does not have to take the college entrance examination, so it is others who are worried, not him.

...

On July 5th, Xiang Nan set off for Yanjing. After reuniting with the representative team, they went to Cancun, Mexico, to participate in the International Mathematical Olympiad held there.

Before leaving, Director Pan, Chu Guoqiang, He Yufen, Ling Xiangqian and many other people saw him off and encouraged him to get good grades in the exam.

Xiang Nan agreed one by one, and set out on the road with everyone's expectations on his back.

On July 7th, the delegation arrived in Cancun.

Cancun is the largest tourist city in Mexico. Surrounded by the sea on three sides, it has beautiful scenery and one of the ten most beautiful beaches in the world. It receives millions of tourists every year and is quite popular.

It not only has beautiful scenery, but also has a pleasant climate. Even in the scorching heat of July, its average temperature is only 25 degrees, which is cool and refreshing.

It just rains more, July is the rainy season, and it rains almost every day. And when it rains, a rainbow will appear, which is very beautiful. So Cancun, in the Mayan language, is exactly [crock pot hanging at one end of the rainbow], which means joy and happiness.

However, Xiang Nan and the others had a task to do, so they didn't have time to enjoy the beautiful scenery, the beach and hot girls, so they stayed in the hotel and started preparing for the exam.

The International Mathematical Olympiad will start on July 8th and end on July 19th, which is 12 days. The competition will be held from July 12th to 13th, and the next five days will be for academic forums and sightseeing.

The results of the competition will be announced on July 18, the closing ceremony will be held on July 19, and then everyone can go home.

There are still five days before the exam, and everyone is still making the final sprint.

Although Xiang Nan was sure, but everyone studied so hard, he was too embarrassed to go out to play by himself, so he had to stay in the hotel and study with everyone.

...

In the next few days, Xiang Nan and others attended the opening ceremony, listened to some lectures, and watched some programs prepared by the organizer.

To be honest, the customs of Mexico are quite good, especially the traditional Indian dance, which has a primitive and rough beauty.

On July 12th, the exam officially began.

Xiang Nan's six people were taken to different examination rooms to avoid cheating.

The test time is four and a half hours, and there are three major questions in each test, each with seven points.

For Xiang Nan, these questions are very simple.

Especially for the third question, he only took two steps to prove that question.

On July 13th, the second exam will continue.

The test time is four and a half hours as usual, and there are still three major questions, each with seven points.

Xiang Nan answered the questions easily, and within an hour and a half, all three major questions were solved.

In order to avoid mistakes, he checked it over and over several times.

After finally confirming that it was correct, he applied to the invigilator for a break, and then went to the lounge next to him to eat and drink until the end of the exam.

...

After the exam, the rest of the time is devoted to lectures and travel.

In order to let guests from all over the world appreciate the charm of Cancun, the organizer has also prepared a lot of tourism projects. Such as the Mayan ruins of Tianjing, Xel-Ha Water Park, Cancun Beach, and the Mayan Museum, etc., opened Xiang Nan's eyes a lot.

He also took the opportunity to buy some Mexican specialty gifts, such as silverware, pottery, blankets, etc., and planned to take them back to his parents and friends.

Compared with his ease, Xie Bing, the leader of the Chinese team, was a little anxious.

Because the questions of this Olympiad test are much more difficult than before, he is very worried that the Chinese team will lose this time.

...

Time passed day by day.

Seeing July 18th, the day when the results were announced, everyone came to the venue, waiting for the results on the bulletin board.

Compared to everyone's anxiety, Xiang Nan seemed much more relaxed.

He was wearing earphones, squinting his eyes, listening to the song Ling Xiangqian downloaded for him, "The sparrow outside the window, talkative on the telephone pole..."

At this moment, a sudden exclamation made him open his eyes immediately.

On the bulletin board, the results of the competition were already displayed.

Among the top sixteen contestants with full marks, Xiang Nan's name was on the list.

In addition, the other five Chinese players also all got high scores.

At the same time, the Chinese team won the championship of the International Mathematical Olympiad with a total score of 242 points, 32 points higher than the second-placed US team, which can be said to be the winner!

Seeing this result, Xie Bing breathed a sigh of relief.

At this time, Xiang Nan hugged happily with the team members.

Having achieved such good results, they can be regarded as a credit to the country, and they did not come to Cancun for nothing!

...

In the evening, the organizer officially held an awards ceremony to present awards to the winners.

A total of 513 contestants from 90 countries and regions participated in the Olympiad. Divided according to the proportion of awards, there are 42 gold medals, 79 silver medals, and 134 bronze medals.

Xiang Nan's six people all won the gold medal, which is the only one among all participating countries, which is naturally glorious.

After receiving the medals, trophies and medals, Xiang Nan and others returned to the stage to do their job, and were waiting for the organizer to announce the next session.

At this moment, Mr. Charlie Fortman, the representative of the sponsor, announced again, "In this competition, when solving the third problem, a contestant used a very ingenious method and solved it in only two steps. prove.

His idea of ​​solving the problem amazed all the judges and commented that it is "the most exciting solution in the history of mathematics competition". Therefore, after deliberation, the judges decided to award him the only special award in this competition. He is Chu from China! "

Hearing what he said, Xiang Nan couldn't help being taken aback.

I didn't expect that I would win a special award for the solution method I came up with to save trouble. You should know that the International Olympiad Special Award is only awarded to those contestants who have unique ideas in solving problems and are more concise than standard solutions.

If it is said that it is as difficult as heaven to get full marks in the International Olympiad, then it is as difficult as heaven to win the special award.

Since the International Mathematical Olympiad, only four special awards have been awarded, which shows its scarcity.

There is no shortage of perfect score players in China. Since the competition in 1985, there have been 50 or 100 full score players. But this is the first time I have won a special award.

So hearing that China's Chu Tiankuo won this award, team leader Xie Bing almost went crazy with joy. This is really the icing on the cake, the finishing touch.

This trip to Mexico was completely complete!
