The Double Ninth Festival poem to wish the elderly good health is as follows:

1. Remembering the Shandong brothers on September 9th: Alone in a foreign land, we are strangers. During the festival, we miss our relatives even more and know where our brothers are from afar. Mo Ying is missing one person.

2. Climbing the mountain in nine days: The geese first fly in the autumn shadow of the river, and they carry the pot with the guests on the green Wei. It's rare to smile in this world, and I must return with my head full of chrysanthemums. But if you match the cheese with the festive season, you won't be able to visit and hate the sunset. This has been the case throughout the ages, why should Niu Shan be alone in his clothes?

3. Things to do on September 10th: I climbed up yesterday and will do some muscle lifting today. Why is the chrysanthemum so bitter? It suffers from these two double suns.

4. View of the Xuanwu Mountain Tour on September 9th: Look at the mountains and rivers on September 9th, return to your heart and look at the accumulated wind and smoke. Drinking golden flower wine in a foreign country, we feel the sorrow of the wild geese together thousands of miles away.

Information expansion:

The Double Ninth Festival is a traditional Chinese folk festival, which falls on the ninth day of the ninth lunar month every year. The number "Nine" is a yang number in the "Book of Changes". The two yang numbers "Nine and Nine" overlap each other, so it is called "Double Ninth Festival"; because the sun and moon both coincide with nine, it is also called "Double Nine". Ninety-Nine Returns to True Truth and One Yuan Begins. The ancients believed that the Double Ninth Festival was an auspicious day.

In ancient times, people had the custom of climbing high to pray for blessings, worshiping gods and ancestors, and drinking banquets to pray for longevity during the Double Ninth Festival. It has been passed down to this day, and connotations such as respecting the elderly have been added. Climbing high to appreciate autumn and being grateful and respectful to the elderly are two important themes of today's Double Ninth Festival activities.

The Double Ninth Festival originated from the worship of celestial phenomena. It started in ancient times, became popular in the Western Han Dynasty, and flourished after the Tang Dynasty. According to existing historical data and textual research, in ancient times, there were activities to hold harvest festivals to worship heaven and ancestors in the autumn season; the ancients held sacrifices to the emperor of heaven and ancestors in September when crops were harvested, to thank the emperor of heaven and ancestors for their kindness. This is the Double Ninth Festival as an autumn festival. The original form existed for the harvest ritual activities. The Tang Dynasty was an important period when traditional festival customs were integrated and finalized, and the main part of them has been passed down to this day.

During its historical development and evolution, the Double Ninth Festival has been a blend of various folk customs, carrying rich cultural connotations. In folk customs, "nine" is the largest number, which means long and long life. It expresses people's blessings for the elderly's health and longevity.

On May 20, 2006, the Double Ninth Festival was included in the first batch of national intangible cultural heritage lists by the State Council. The "Law of the People's Republic of China on the Protection of the Rights and Interests of the Elderly" revised and passed by the Standing Committee of the National People's Congress in 2012 stipulates that the ninth day of the ninth lunar month every year is the Senior Citizen's Day.
