Is Zhang Xueliang's Lao Zhangman Zuo Lin a good guy or a bad guy?

Zhang is a middle figure, and the good guys and bad guys can't tell clearly. But one thing, Zhang is definitely not a Japanese lackey as mentioned in history books. He wandered among various forces and benefited the people in Northeast China. I dare say that from Zhang to now, no regime in Northeast China has been established as well as the Zhang family. Among the major universities in Northeast China, Northeast University (including Northeast Normal University) was built by Zhang Xueliang, and Northeast Normal University was built by Zhang Xueliang. The aircraft factory in Shenyang was built by Zhang Xueliang, and the military factory was originally built by Zhang Xueliang. Without the Zhang family and his son, where did the old industrial base in Northeast China come from? It is because of their construction that the heavy industry foundation of new China was laid. My friend, if you are from the Northeast, you should know their contribution to the Northeast, so you wouldn't ask such a question. By the way, I asked this question when I was a child. My grandfather replied that he was both a good man and a bad man, good because he didn't bow to the Japanese, and bad because he killed Li Dazhao. I was only three years old at that time, but now, Zhang has many good ingredients.
