I'm looking for a voice, looking forward to it singing the notes in the shadow to you. Record a book, an author, a film and the love between it and life. I love books and movies, but also love life. I hope we all have endless years of flowing water.

Listen to vegetarian music, taste vegetarian tea, read vegetarian books, and write vegetarian heart. Even if you live in poverty for a lifetime, you will feel at ease. Just want to leave a touch of light in the depths of the world of mortals. I just want to find a heart in this vast sea of people. Love to read a few words, often listen to a few songs, enjoy a few teas, and occasionally insert a few flowers. I have nothing to ask for in my life. I just watch the flowers bloom and fall.

I read books only for entertainment. Sometimes when I find them interesting, I gladly write them down. I dare not say that all hands make a mickle, but I will cherish myself when talking about it. A great man said that the world of science is like an ocean. He is like a child playing on the beach. He is very happy when he occasionally picks up a few shells. The metaphor of the sea can also be used as a vast literature and history. Walking in the classics of literature and history, occasionally picking up some leftovers is also exciting.
