The young man's startling glance locked him for the rest of his life. The story of Tang Kueh and Lin Xiao is a long wait spanning seven years. In the past, we met briefly and then parted suddenly, and we met again after a sea of people came and went. After overcoming the barriers of distance and time, they faded away from youth and youth, and they came together with their unchanging hearts. They had three meals of fireworks, accompanied them day and night, their relatives and friends were healthy, and their children were around their knees. The long and distant waiting turned into a stable and long-lasting perfection.
