Han Du and the two of them added WeChat friends to each other before arriving at the station.

"Okay, Han Du, if you encounter anything urgent in Harbin City, you must come to us, and we will definitely help if we can." Yiya was a little reluctant.

"Okay, if there is any difficulty, I will find you and Qiangsu." Han Du smiled gently, the three of them just met in Pingshui, and it was rare to be able to treat each other so honestly.

When Han Du got off the high-speed train, the car quickly started to go to the next station, and he hurried out of the train station.

Coming out of here, Han Du opened the map on his mobile phone, searched the geographical location of Xijiang University for Nationalities, and found that it was a little far away from here, so he took a taxi over.

In Harbin City, where the traffic roads are developed, the online car-hailing service also drove for more than 40 minutes to arrive at the West Xinjiang University for Nationalities.

Han Du didn't enter the school immediately, and found a hotel outside the school to stay first, and this trip was estimated to take a few days, so he opened a room for three days.

When he arrived at his room, Han Du lay on the bed, flipped through his mobile phone, and found that the battery was low, so he ordered a charger and snacks through the online platform of a nearby supermarket, and ordered himself a hamburger meal by the way.

Waiting for these things to be delivered, Han Du ate while charging.

After eating and drinking, he left the hotel and officially entered the Western Xinjiang University for Nationalities.

When he arrived on campus, Han Du sat down in a gazebo and pondered how to take action.

According to card 5, do you want to know some secret of your parents? They were once the spiritual pillars of an expedition team, the trendsetters of the expedition world, returning to the place where they first met, to see why they met and fell in love, and embarked on the road of exploration together.

The purpose of this limited scenario mission is very clear, which is to see why they met and fell in love and embarked on the road of adventure together, so the first thing is to find people who know them well in the school.

His parents have graduated from Xijiang University for Nationalities for more than 20 years, and it is very unlikely that they will find someone who knows them, because the people they knew back then are estimated to have already left school and are now all in Tiannan and Haibei.

Han Du took out a cigarette and lit it, smoking the cigarette and slowly thinking about a way, and soon a cigarette burned out, and he was still at a loss.

So he lit a second cigarette, smoked it, and suddenly jumped up because he had thought of a way.

At present, you can only start with the teacher who has been teaching for the longest time in the school, and as long as the teacher has been teaching longer than his parents have been away from school, it is possible to know his parents.

Han Du took out his mobile phone, found the official website of Xijiang University for Nationalities, and searched for the school's teachers in it, but found that only some of the excellent teachers' information was in it.

This information is obviously not complete, but it can still provide some information for Han Du, for example, there is one of the oldest teachers, named Chang Yugang, who is the most prestigious professor level teacher at Xijiang University for Nationalities, who has been teaching for 45 years, and the official website says that he has dedicated his life to Xijiang University for Nationalities.

Han Du can only try his luck with this old professor Chang Yugang at present, through the information released on the official website, there is just a public class of this old professor today, Han Du plans to listen to it, so as to find a chance to talk to him.

The time of the open class was just half an hour later, Han Du remembered the classroom number, classroom No. 35 on the fifth floor, got up and rushed to the teaching building.

The teaching building of Xijiang University for Nationalities is very large, there is no problem with accommodating tens of thousands of people, Han Du took the elevator to the fifth floor, and the first thing he saw was classroom No. 11, and he looked for it along this number, and it didn't take long to find classroom No. 35.

The classroom with more than 300 seats was already full of people, and many people were still crowded into places without seats, intending to stand and listen to Professor Chang's class.
