The world is hot and cold. Fu Yan has experienced these four words thoroughly in the past few days. The friends who used to surround him all called "Brother Yan" more affectionately than anyone else. Now when we meet someone on the street, we either pretend not to see them and turn away, or they treat them as if they were watching a joke, with eyes full of contempt and ridicule. Even the old nanny who had worked in the family for five or six years dared to point at him and scold him before leaving. "Fu Yan, let me tell you, don't think that you are still that young master! Now you are a lost dog! If it weren't for your mother being kind to me before, I wouldn't even give you a drink of water!"
