Tang Jing told him that she had called Shasha's mother. So, when Shasha's mother heard that the advertisement was 10 minutes long, she was dumbfounded and said that she would have to ask her husband first to see if it could work or not, but she especially told Su Yang not to have any high hopes. After all, it was a long video, so it was going to be hard to get it included regardless of what show it was.
Hence, when Tang Jing heard what Shasha's mother said, she was afraid that Su Yang might hold too much hope, so she quickly called Su Yang to inform him.
Instead, Su Yang only told Tang Jing that he understood the situation.
At night, Su Yang returned home and continued to read at home slowly. That day, he was reading "Robinson Crusoe" which meant that the books he was reading were getting more and more complicated as he began reading all kinds of books. As a result, this allowed him to be able to continuously expand his knowledge.
