In this fast-paced, high-stress era, we often get caught up in work, study, and the trivia of life, neglecting the most basic yet warmest connection between people – greetings. Every November 21st is designated by the United Nations as "World Greeting Day," a day to remind us to slow down and convey love and peace to those around us and to the world at large.

World Greeting Day originated in 1973, initiated by then UN Secretary-General Waldheim. He hoped that by establishing such a day, people worldwide would be encouraged to cross racial, cultural, and national boundaries, using simple and sincere greetings to enhance mutual understanding and friendship. On this special day, whether it's a face-to-face smile, a "hello," a "good morning," or a "wish you well" through a phone call, text message, or social media, they all serve as bridges connecting hearts, making the world more harmonious and warm.

Don't underestimate the power of a simple greeting; it holds immense energy. In interpersonal communication, a greeting is the key to opening the door to conversation, instantly bringing people closer.

Example 1: During the pandemic, a nurse, amidst her busy schedule, never forgot to video call her parents every day to assure them of her wellbeing with a "Mom and Dad, I'm doing fine. You take care of yourselves too." This simple greeting brought peace to her elderly parents at home and gave them the courage to keep going.

Example 2: On a cold winter morning, a passerby saw a street beggar and instead of ignoring him, walked over and gently asked, "Are you cold? Is there anything I can do to help?" This simple greeting made the beggar feel the long-lost care and warmth.

These examples prove that a simple greeting not only conveys our concern and love but also plants seeds of hope in others' hearts, inspiring them to face life with courage.

: On social media, start a "#WorldGreetingDayChallenge," inviting friends to share how they greeted different people (family, friends, colleagues, or even strangers) today and encouraging more to join in. For instance, share a particularly heartwarming greeting or a creative way to greet, like making a handwritten card with a greeting.

: While electronic communication is fast and convenient, there's no substitute for the heartfelt weight of a handwritten greeting card sent to distant relatives or friends. On the card, you can pen down your thoughts and blessings, letting the recipient feel your genuine emotions.

: Participate in or organize a community event like a "Free Hug Day" or "Smile Pass-On," using body language and smiles as the most direct forms of greeting, allowing warmth to flow between people. Such activities not only strengthen neighborly friendships but also foster a more harmonious community.

: Leverage modern technology to video call or chat online with people from different countries, expressing greetings in their respective languages, experiencing cultural diversity, and enhancing international understanding and friendship. Choose a country you're interested in, find local friends through social media or international friendship platforms, and share your cultures and lives with them to celebrate this special day together.

In this era filled with challenges and opportunities, World Greeting Day is not just a simple commemorative day but a spiritual awakening. It reminds us that no matter where we are or what difficulties we face, a simple greeting can be a ray of light illuminating others' lives, making the world a better place.

Let's start from today, not just on World Greeting Day, but every day, to freely give our smiles and greetings. Let's prove through actions that love and peace begin with a simple hello. On this special day, why not pick up your phone now and send a warm greeting to your family, friends, or someone you've been wanting to reach out to but haven't had the chance?
