Bi Bi sat and studied with him. He advised: "You are determined to study well. If you want to study well, you must sit still and concentrate."

Let me spell it out for you.Yes. "I go to school, the baby cries,"Good, Bi Bi spelled correctly, then read it all at once. When did you teach me that? I'm so proud of you! Just like that, Bi Bi spelled and read fluently. By the time he finished reading the sentence "Watermelon, peach is round", Bi Bi naturally looked at him and grabbed a brush to draw on the table. He reminded:Bi Bi, focus! Bi Bi was startled, but still asked:Sir, what is concentration?Well, whatever you do, you have to pay attention to doing it well, don't look around, don't do other things.I'm still focused. But for some reason, my hand keeps wiggling on its own, not me! He said seriously:You can't blame it on your hands. You control your hand, not your hand controlling you. Can you give me the pen?Yes! – Bi Bi answered and then took the pen and gave it to him.See, you're the one controlling the hand, right?Yes.Then sit still, continue to spell and read. Bi Bi sat still, but suddenly her head and butt itched, so she raised her hand to scratch her head and then her butt. He spoke more seriously:Let's focus! Naturally, Bi Bi's tears flowed. Bi Bi wanted to concentrate but it was so itchy, it was not like Bi Bi didn't listen to him. He softened his voice:Do you need me to apply some medicine now?No.So put your hands on the table, sit seriously and spell and read. Bi Bi did as he said: "Watermelon is very delicious. My teacher... me. Wait for the jackfruit to fall somewhere... somewhere". Bi Bi spelled, and read three sentences in a row, smoothly. He complimented:You can concentrate now, very well. Suddenly, Bi Bi felt relieved, no longer itchy, but just liked to sit with her hands on the table and spell and read. But, the lesson was over. He said: "Okay, let's rest, dear." Bi Bi stood up and spelled out: "When in doubt, ask for a break. That's right. Oh, it's heavy!"
