黄老师是一位上课时很认真，很有责任感，常用最简单，最容易懂的方式，把复杂的科学知识，再注入有趣的元素，让我们每位同学都了解，而且把这些知识若烙印般的存在于我们的脑海中。
其中一个黄老师仿佛若燃烧着的蜡烛，燃烧自己，照亮别人的，那就是他要展示random movement, 他点燃了一根香烟，吸了一大口，再将烟吹入特制的显微镜的装置中，就轮流让我们每位同学上前来观察，看看random movement 到底是怎样的，老师的牺牲，真是敬佩 🙏🙏🙏。。
但，中学时期某一个中午，上黄老师的科学课，骨子里有些傲气的我和同学开玩笑，嘻嘻哈哈的，被黄老师看在眼里，他于明喻来训导我，说道：
‘’。。脑子要时常像空或半杯水的杯子，这样才能好好的，可再装入水，那才能很好的吸收知识，要时时刻刻保持谦卑的心，虚心的学习；而不是有了小小成就，就扮成个有高傲脑子的人，仿佛若装着满满水的杯子，水装都装不进去，会溢漏出来，就是高傲性格的将再也无法有效的吸收外来的知识，日复一日，年过一年，终将荒废学业，到头来，一事无成，蹉跎岁月。。‘’
哇！真的被老师一语惊醒梦中人，仿佛若把一桶冷冷的冰水往我头上淋，就以上这场景，使我常常想起，让我永远铭记于心头，时常要虚心学，谦卑的学，别扮高傲。。
这画面场景，永远在❤中，永远永远！
My science teacher Mr Ng HT
My secondary school science teacher, Mr. Ng, was a very dedicated and responsible teacher. He used the simplest and most understandable methods to explain complex scientific knowledge, infusing it with interesting elements so that every student could grasp it and imprint this knowledge in our minds.
One of Mr. Ng's act was like a burning candle, sacrificing himself to illuminate others. When demonstrating random movement, he would light up a cigarette, take a deep drag, and blow the smoke into a specially designed microscope. He would then take turns having each student come up to observe what random movement looked like. His sacrifice was truly admirable 🙏🙏🙏.
However, one noon during Mr. Ng's science class in school, I, with my inherently arrogant nature, joked and laughed with my classmates. Mr. Ng noticed this and, with a subtle reprimand, said to me:
".. The mind should often be like an empty or half-full glass, so that it can be properly filled with water, in other words, to absorb knowledge. One must always maintain a humble heart and learn with an open mind; rather than becoming arrogant after achieving a little success. Like a glass full of water that overflows, an arrogant personality will prevent the effective absorption of external knowledge. Day after day, year after year, one will waste their studies, ultimately achieving nothing and squandering their youth.
Wow! The teacher's words truly awakened me from a dream, as it's like a bucket of cold water had been poured over my head. This scene will often remind me, and I will forever remember it. Always learn humbly and without arrogance.
This scene will forever remain in my ❤️, forever and ever!
