"Where's Brother Zixuan? Why isn't he here?" Qin Mucheng asked curiously.

Ji Yuanyuan quickly explained, "We moved to a house in the city yesterday. Today, my mother brought my brother to a training class. She wants my brother to participate in the Mathematical Olympiad competition."
"Really?" Qin Mucheng's eyes lit up, "I'm quite familiar with this, including the time and format of the major tournaments. If there's anything he doesn't understand, he can call me anytime."
Qin Junshan listened and became smug, "Our Mu Cheng has been participating in math and physics competitions since he was young. He knows all kinds of competition systems."
