In the Pentium era, Chang Hanqing had no concrete realistic prototype, but his deeds did exist at that time and were the epitome of many people.

In order to make "Pentium Age" more real and closer to life, screenwriter Wang Chenggang interviewed hundreds of engineers and craftsmen who had experienced the development of China railway. One of the prototypes of Chang Hanqing's role is Liu, an academician of China Academy of Engineering and director of Zhuzhou Machinery Expert Committee.

The ending of Chang Hanqing

The ending of Chang Hanqing's "Pentium Age" is a brilliant marriage and a win-win love career.

There are mainly three women who like Chang Hanqing in the play. One of them is tonya, an expert on Soviet issues, the other is Bai Manning, a suitable woman, and the other is Jin's talented Judge Gao.

Tonia left the Soviet Union, and there was nothing between her and Chang Hanqing. Bai Manning and Chang Hanqing were childhood friends, but Chang Hanqing didn't like Bai Manning. In the end, it was Jin Huihuang who fell in love with Chang Hanqing.
