又到圣诞节了，2021年即将到来。在这两年的交叉点，Dervos当然会举行庆祝活动来纪念这一重要时刻。在圣诞节的早上，我们的秘书为我们每个人准备了一袋糖果。除了糖果，每个人还有一个苹果，这是中国平安夜的一个不同寻常的流行传统。这个传统的产生是因为“苹果”的中文发音与“平安夜”谐音，它代表着美好的祝愿。乒乓球，作为中国最受欢迎的运动项目，在过去的几个月里在德沃掀起了一股热潮。当圣诞节遇到了乒乓球，我们决定举办一个特别的，中国特色的游戏——乒乓球比赛。我们分成4支队伍，经历了一系列的比赛——单打、双打和混合双打，以决定谁能笑到最后。令人惊讶的是，我们真的为开幕式准备了奖杯、剪彩和横幅。太有趣了。 That was a funny and stressful afternoon, you have to say. Because infrequently we took it so seriously that everyone practiced and performed hard, longing for the laurel of the team. Though every team was brilliant no matter the result. And unarguably the best play went to West Lin who led his team to runner-up when the situation was not optimistic for him. In the end of this article, Dervos is honored to spend another year with our customers and friends. We sincerely wish you a happy holiday season and a best new year.
