How long does it take for one liang of baijiu to not be detected in an alcohol test?

It typically takes 6 to 8 hours for one liang of baijiu to not be detected in an alcohol test, but this also depends on the amount consumed and the individual's ability to metabolize alcohol. For a normal person who consumes less than 150 milliliters of baijiu, it usually takes around 6 hours for the alcohol to be undetectable. Excessive drinking may prolong this time. Individuals with liver diseases such as cirrhosis may metabolize alcohol more slowly. Driving under the influence of alcohol will result in a six-month suspension of the driver's license and a fine. If caught driving under the influence again after a previous penalty, the offender may face up to ten days of detention, additional fines, and revocation of the driver's license. Drunk driving will lead to being restrained by traffic police until sober, revocation of the driver's license, criminal liability, and a five-year ban from obtaining a new driver's license.
I remember checking this after drinking a shot of baijiu at the last gathering. A standard 50ml shot of high-proof baijiu contains roughly 20g of alcohol. The average person metabolizes 10-15g of alcohol per hour, so you'd need at least two hours. But you really shouldn't push it – a friend with slower metabolism still blew 15mg/100ml three hours later. High-sensitivity breathalyzers are even riskier, especially when your breath still reeks of alcohol right after drinking. To be safe, wait at least four hours before driving. If you're sleep-deprived or have liver issues, waiting overnight is wiser.
The fitness coach said that alcohol metabolism varies greatly depending on one's physique. For someone like me who frequently lifts weights, after drinking one liang (50ml) of 53% Baijiu, I tested and found my breath alcohol level returned to zero in two hours. The coach mentioned that people with higher muscle mass tend to metabolize alcohol faster. In contrast, my colleague Lao Wang from the next office, who is overweight, takes over four hours to test negative after consuming the same amount. Faster blood circulation post-exercise does help, but the most reliable method is to carry a portable breathalyzer and confirm a zero reading before heading out. Metabolism slows down in winter; I once nearly got into trouble because I overlooked this.
