A little too many words "When Happiness Knocks on the Door" was seen by chance, but it moved me so much, so long ago. The plot in the film is so profound. Chris, a black man, was an ordinary medical device salesman. His wife could not bear the economic pressure and left him, leaving his 5-year-old son Christopher to live with him. Chris had only 21 yuan left in his bank account. Because he had no money to pay the rent, he and his son were expelled from the apartment.

Father and son are still striving for happiness. They began to live in shelters, but faced with limited beds, the man who ran like a cheetah sometimes had to use the explosive force of the grassland to fight. The son fell asleep on the bed of the simple shelter, while the father was still busy repairing the medical equipment sold, or turning over the thick written examination book.

The wallet was badly worn, and it was too flat. Every piece of money was familiar. The boss wanted to borrow 5 yuan, hesitated, rubbed the note, and finally gave the money away. Sell blood. The blood seeps into the plastic bag, which is the last thing a man can offer. With the money from selling blood, Chris still went to buy electronic components. A little hope, we must insist.

What is the most sad thing for parents is that their children's poor wishes cannot be met. Christopher's only doll, "American Hero", fell to the ground during a traffic jam. The 5-year-old boy was extremely sad. Under Chris's hard expression, he read the ferocity and pain in the face of difficulties. However, no matter how deeply hopeless, they did not destroy the kinship between father and son and their faith. They believed that happiness would always fall on themselves. "You are a good father", Christopher wandered around with his father, but the child's heart, the weight is the same as the angel.

Chris eventually became an employee of the investment company, seemingly indifferent white bosses, and at this time showed their slight warmth. He held back his tears, picked up his belongings trembling, and walked into the vast sea of people. In the midst of the bustling crowd, Chris raised his hand and applauded for himself. The silent, heavy applause was cheering for himself. In fact, Christopher's "American hero" is not lost.

This is a very typical "American dream": one can realize his dream through his own efforts, and happiness will knock at the door. Many people tend to focus on the establishment of dreams, and often ignore the hardships of the process. In particular, when faced with a seemingly hopeless reality, how many people will persist and how many will give up? Life is always correcting, and reminds us that people who follow the tide are always more likely to reach the other side of success. However, there are some people who are willing to go against the current. I believe that this is the director's encouragement to the rebels.

The anonymous Hong Kong graduate later graduated with a doctor's degree and found a good job with a beautiful wife and lovely children. The strong man said in his post, "What can't stick to it?"? As long as there is a dream
