Traveling back to Hong Kong in the 1990s that we are both familiar with and nostalgic for, he set off a bloody storm in the world and rewrote Hong Kong's business legend. When the excitement of life is over and he returns to ordinary life, he will hand a bowl of hot wonton noodles to frustrated people in a tea restaurant, stop young people who are about to make mistakes in the alley, and build a bridge for lovers in the wind and rain. There are still grievances in the world, and there are still major cases in the police station, but here in Lin Zilin, there will always be a cup of frozen lemon tea and the sentence "Speak slowly when you have something to say, and the most important thing is to be happy." This is a love letter to old Hong Kong drama, a gentle adventure about fireworks and human love. In the end, we will find that the most moving thing about Hong Kong dramas is never the power and wealth at the peak, but the tenderness and loyalty engraved in the bones, and the human fireworks that never fade away in the long alleys of the market.
