There was nothing to say along the way, but upon returning to Star City, his alma mater gave him a big surprise.
Old Zhang was no longer satisfied with just hanging a red banner at the school gate for celebration. This time, he directly rented one of those arch-shaped balloons typically used for celebrations, standing it at the school gate, with an air blower borrowed from the security room blowing loudly.
"Warmly celebrating our student Qiao Yu in grade one for entering the IMO national training team with his impressive result as the first place in the 66th CMO nationwide!"
Actually, Old Zhang wanted to add a few more words on the balloon, like breaking the zero record or defeating the four top schools of Star City. But the balloon was only so long, and adding more words would require the font to be smaller, so he had to give up.
