"Kite" has been broadcast for so many years, but a good drama can withstand repeated memories. The suicide of Lin Tao has always been a big controversy, and even many friends feel that Lin Tao's death was designed by Zheng Yaoxian in advance. If that were the case, it would be a little frightening. Zheng Yaoxian really deliberately left evidence to let Lin Tao know that he was an underground party of the Ccp, and as a senior agent who had received special training from both the Kuomintang and the Communists, he was a senior spy who never left any trace of his work, so how could he make such a low-level mistake? There should be the following reasons for this:

First, Zheng Yaoxian's communist organizational relationship has been out of touch for many years, and at this time the Shancheng Public Security Bureau is also tracking down whether he is a military command agent, so he is also very aware of his situation; on the one hand, under the pseudonym Zhou Zhiqian, he can easily be accused of being a military commander Zheng Yaoxian; on the other hand, his upper line is dead, but his identity as a communist will not be clear for a moment and a half, and then the Kuomintang agents lurking within our party have not been cleaned up. If he is proved to be a military commander, he will either be shot by the Kuomintang agents who are regarded as the most heinous crimes of our party, or he will be assassinated by the enemy agents lurking inside our party.
Second, the letter that Zheng Yaoxian wrote to the head of Beijing became the fuse for Lin Tao's suicide. Lin Tao once seduced Zheng Yaoxian on the orders of the Central Unification, and many people in the military command knew about this matter, and as long as someone pointed out Lin Tao, it was tantamount to confirming that Zhou Zhiqian was Zheng Yaoxian. But when Lin Tao was cleaning up the house, he inadvertently found the traces left by Zheng Yao's first writing on the table, and learned that Zheng Yao was first a Communist agent, the unbelievable fact of kite. The battle between faith and love started the final battle in Lin Tao's heart, and in the end, Lin Tao still failed to escape the shackles of love, and chose the most tragic way to disfigure and commit suicide for Zheng Yaoxian, not only to avoid Xu Baichuan's identification and protect Zheng Yaoxian. Also in the preservation of their own child Zhou Qiao. If Lin Tao did not disfigure and commit suicide, as soon as her identity as an agent of the Central Command was exposed, she and Zheng Yaoxian would all fall into an unbearable situation.
Third, the reason why Zheng Yaoxian told Lin Tao by revealing his handwriting was that he was worried about telling Lin Tao in person that she would be too excited after she knew, which was equivalent to giving her a time to accept reality. But as long as Lin Tao's identity is confirmed, whether he admits it or not, there is no way to cover it up. However, because Lin Tao shared a piece of true feelings for himself and his own feelings for Lin Tao, he could not directly end Lin Tao's life, and the best way was for Lin Tao to commit suicide. Wanwan did not expect that Lin Tao not only committed suicide but also disfigured because he loved Zheng Yaoxian deeply, which made Zheng Yaoxian feel extremely guilty, and Zheng said that Lin Tao truly loved his own skin bag. From this guilt can also be glimpsed, the letter may be deliberate and there is no way to do it, can only use Lin Tao's feelings and gratitude for himself, what he never expected is that Lin Tao, as a former central command agent, ended his life in a disfigured way in order to cover him.
In the end, Lin Tao's suicide was also brought about by her inability to bear her personal beliefs. She gambled her life not believing that the beloved sixth brother was from the enemy's party. If she chooses to stick to her faith, killing Zheng Yaoxian is the best way, but she chooses a diametrically opposed routine. Completely betrayed the organization and pointed the finger at himself. Although Zheng Yaoxian and Lin Tao come from two different camps, they are a family that loves each other and enjoys the joy of going around the knees, trusting each other and merging into one, which can be called a couple of suffering couples who have been in love with each other. At the same time, Lin Tao's unswerving love for Zheng Yaoxian until his death is very admirable.
