After five years of hard work, Lin Yu was publicly promised a huge year-end bonus at the company's annual meeting, but the amount that finally arrived was only 19 yuan. Once a contributor, he became the laughingstock of everyone overnight. Facing deception and criticism, he did not get depressed or compromise, but resolutely chose to leave. After joining Dinghui, Lin Yu led the team to overcome difficulties, breaking through core industry technical problems one after another, and proved himself with solid professional strength. All the hardships in life serve as paving stones, and the accumulated skills are the most solid foundation for a comeback against the wind.
