Chen Dalei: Be dignified and courageous. Can lead the sixth division well, fight wisely and bravely, and never fear the enemy. His temper is as stubborn as Erlei's, and he and Erlei are good brothers, courageous and resourceful. It is the pride of the New Fourth Army. Being modest and kind, although he is a commander, he never puts on airs. Attach importance to feelings. Straightforward and simple. Humor and cheerful personality. Focus on your own career and care about smoothness. Can educate and lead his soldiers well, (there is an episode in which he tells his father's story to his soldiers. ) murderous, no matter how strong the devil is, there is a momentum. If you want to defeat them, you are not afraid of sacrifice. (It seems that in more than 1 episodes, after the war in the evening, they will face death tomorrow, but they are still leisurely.) That's all. I swear I definitely summed it up myself. That's all.
Shun Liu: Like Da Lei, the temper is born with an unrestrained character. Just like Da Lei said, he is as free as a wolf in the mountains. Finally, we can make the right choice under the struggle of revenge and discipline. Careless and attached importance to his family, but in the end, after the baptism of war, he chose not to take revenge. A good shot, he admired the commander from the bottom of his heart.
I don't know if it will help you to sum this up.
Do you remember what Da Lei said at the beginning of the first episode? He said that Er Lei is a hero, but I can't put him in the hero book, so I can only tell you our story.
