Yesterday marked the 5th anniversary of the formation of this group. 😁
This group was formed to provide students with a learning platform during the COVID-19 lockdown. It also aimed to encourage students to stay strong, be determined, and do their best in learning chemistry so they can achieve the goals they have set for themselves.
I firmly believe that as long as you have determination, perseverance, put in the effort, avoid making excuses, and are willing to believe in yourself, you will definitely reach your goals in the end. Let’s work hard together and cheer ourselves on!💪
昨天是这个小组成立五周年的纪念日。😁
当初成立的目的是为了在COVID-19 封锁期间，为学生们提供一个学习的平台。同时也希望鼓励学生们要坚强、坚定，并尽力学好化学，以实现自己设定的目标。
我始终相信：只要你有决心、有恒心、肯努力、不找借口，并愿意相信自己，最终一定能够达标。让我们一起为自己加油、努力！💪
