Who is Beethoven's wife?

Of course this is a good question, you have to ask me. In fact, Beethoven had a wife: Mona Lisa was one of them. At that time, they gave birth to their daughter Ugly Xiang without a birth permit. Because they didn't get the birth certificate, they had to abandon him, so they were adopted by Washington, and later there was the movie "The Ugly Face of Tang Bofu". Absurd questions deserve this absurd answer. Adopt me!
