The origin of wine story "Cheers"

According to legend, the word "cheers" comes from Ireland in the 16th century, people were extremely fond of drinking whiskey, and at that time, there was a rivalry between the nobility, and it was especially popular to murder with poisoned wine. Therefore, in the upper class society at that time, in order to show that there was no poison in the wine, the party would bump the wine glasses with each other before drinking, so that the wine in their respective glasses would touch each other's glasses to show that there was no poison. However, in later years, this "cheers" has evolved into a friendly gentleman's etiquette.
