The two of them went to the Southern Province to carry out a mission and hid it from the old man. They only said that they wanted to return to the Southern Province to visit the martyr park. When the old man found out, he thought that the two of them were going to visit Sun Xueqing. He even planned to accompany them and said, "Your mother has married into the Fu family for more than 20 years, but I've never seen her once. I should go and take a look too.
In order not to let the old master worry, they found a suitable reason. They didn't expect the old master to want to go too. Mr. Fu persuaded him, "Let's wait for the weather to get warmer before going. It's snowing heavily in the Southern Province now. I just saw the weather forecast. It'll snow in the Southern Province tomorrow. If it's not for the fact that it'll snow heavily for the next few days, I wouldn't have asked the two of them to rush back to the Southern Province tonight.
