How old was the author of this novel? How was his standard?

The name was typed Looking out of the window, there was another teahouse two streets away. It was much larger than this one, and its business was naturally much better. A did not go there often. The teahouse was built on a snowy winter day six years ago. In the past six years, A had only stepped into the door of the teahouse called Yuansong Restaurant twice. How could they be ordinary businessmen? The world only knew that Yuansong tea was top grade, but they didn't know what kind of business Yuansong Tower was doing. Five years ago, when he first stepped into the Yuansong Pavilion, it was to find the blue in his heart. Seven years ago, A had already left his home to wander the world. He had practiced swordsmanship since he was young, but he was also tired of the restrictions. His family business was huge, but he had sneaked out and never returned home. A was good at swordsmanship, but he had no intention of being a proper hero. He loved all kinds of young women, but he had never set foot in those places where women were stained with too much rouge. Instead of liking and admiring them, he felt more pity for them. This was the kind of person A was. He had brought them to his bones. Other than women, he also loved the sea. The sea was magnificent, free, and boundless. These words were not considered beautiful. It was probably the beginning of A's love for the sea when he was trapped in a large courtyard when he was young. No one had ever told him about this. He secretly heard it and it became a thought in his heart. Therefore, ever since he left home, the sea became a place he had to visit every day. It was also in the sea that she met the clean and clear blue in his heart. Seven years ago in the morning, A had seen him at the seaside. The cool sea breeze blew the hair of the merman with blue hair. He gave him a light smile, the corners of his mouth curled up into an extremely beautiful arc. The bright morning light coated the merman's blue hair and fishtail with a layer of golden light, like a gentle feather, gently brushing across the clear blue pond in his heart, creating ripples. Later on, he found out the merman's name. He was called B. After that, he would come to the beach every day. When A was alone, B would appear. He was always smiling, and his gentle and lively smile was reflected in A's eyes. It was the clearest sight he had ever seen in his life.
