2. in front of the classroom: don't whip yourself! Two sides: study hard and be an upright person! Life is as simple as grass, don't be afraid of ups and downs!
3. In front of the classroom: there are thousands of volumes in my chest. After the Tianjiao classroom was created, I climbed the road of Tianjiao, slowly complaining and pursuing Excellence! Don't make excuses for retreating, but create conditions for moving forward.
4. In front of the classroom: Look before you leap. Behind the classroom: no regret medicine. Wise and sensible, sensitive and studious. Thick accumulation and thin hair, dripping water wears away the stone, and diligence can make up for the eagle's attack, and the wind is strong and the waves are urgent.
5. Classroom slogan: Ling is at the top of the wind, and I will never regret it tomorrow. Desire is not the rainbow of action, but action is the rain that waters the fruit. Ruthless years have increased and decreased, and youth has both bitterness and sweetness.
