How to write in ancient Chinese in the letters that the ancients expressed their blessings to distant relatives and friends during the Mid-Autumn Festival? Should I write in traditional or simplified

How to write in ancient Chinese in the letters that the ancients expressed their blessings to distant relatives and friends during the Mid-Autumn Festival? Should I write in traditional or simplified Chinese? Simplified and complicated Chinese characters were only carried out after the founding of New China.

The following is from my original, not worth laughing at. For the landlord's reference:

This book is under parents' knees;

Or your Excellency XX:

Or the book is XX:

The bright moon is in the sky, and the Ming River is in shadow. (These two sentences are from Niannujiao Dongting Grass written by Zhang Xiaoxiang in the Southern Song Dynasty. I am very happy to celebrate the Mid-Autumn Festival, and Yu (my elders call me my parents) is even more overjoyed. However, it is a pity that thousands of miles apart, you can't enjoy yourself, you can't enjoy the moon and talk about autumn, and you can't get together (friends try their best to enjoy themselves). Wang Moqiu said, "I miss my relatives twice during the festive season." The ancients honestly didn't bully me! But Yu also tasted the words of her mother-in-law, "I wish people a long time and a thousand miles of good scenery." This is just a long-term expectation! On this beautiful night, I only wish Gaotang good health, peace and joy (to make friends in Gaotang, use "good health")! Although Yu (or Er) is thousands of miles away, it is a pity that I can't meet each other, and I can also solve my worries and thoughts.

Bad boy XX smokes, takes a shower and bows down.

Or a silly friend whom XX worships (or worships)
