Because Yang Zhigang is actually the youngest child in the family. Before Yang Zhigang was born, there were already three children at home. In order to avoid being caught, his family will adopt them to their uncle and change his mother's surname, namely Yang.

Although my brother Guo Jingyu is adopted, he still loves his younger brother very much. When his younger brother couldn't find a crew after graduation, he was invited to his own crew by Guo Jingyu. At first, Guo Jingyu didn't let his younger brother play the leading role. Later, Yang Zhigang performed very well. After gaining experience, he became the protagonist in his brother's works.

Although Guo Jingyu, as an elder brother, takes care of his younger brother, he doesn't just spoil him. After graduation, Yang Zhigang starred in a literary film. When he was complacent, he was severely criticized by his brother Guo Jingyu. Guo Jingyu said that Yang Zhigang should be down-to-earth and start from a supporting role.

In fact, Yang Zhigang's works have always been deeply rooted in people's hearts, but the image is really fixed. The audience likes him very much, which also shows that he is actually capable. As for Erdaozi's criticism, it is estimated that there is not much room for development in Yang Zhigang, but at this age, Yang Zhigang's works should not have much influence even if they are read alone.
