LONG TILING CHANNEL as a chute for fluids within soil, and LONG-NECKED VESSEL, BOTTLE are related to the left element, a person kowtowing in the lordosis position and revealing the anus. It was discovered (somehow, perhaps while administering anesthesia on a battlefield one day) that directly inserting alcoholic beverages into the anus to be quickly absorbed by the colon directly into the bloodstream and bypassing ingestion enabled a satisfactory experience using only a small amount of wine. This technique was not employed in most homes, primarily since this methodology discouraged subsequent use of the bottle orally and due to causing some debate about the change in the wine's flavor, but became highly useful among bivouacked soldiers in the field with limited resources. Legend has it that virtually all modern liquor bottles are formed with a longneck shape, and longneck beer bottles have an anal plug shape, namely a bulge in the bottle neck, for this same purpose of use among troops (either with, or without, alcoholic contents remaining in the bottle):
　「An alcohol enema is a faster method of alcohol intoxication since the alcohol is absorbed directly into the bloodstream. The lower gastrointestinal tract lacks the alcohol dehydrogenase enzyme present in the stomach and liver that breaks down ethanol to make it less toxic for the body. The alcohol will still eventually arrive at the liver, but the high alcohol content could overwhelm the organ. Additionally, consuming the alcohol rectally neutralizes the body's ability to reject the toxin by vomiting. Overall, experts believe that alcohol enemas are a dangerous method to consume alcohol.」
