Martinis should have only odd numbers of olives. There’s a proper way to choose a glass for different beer types. You can offend people by how you drink whiskey. Baijiu has also evolved a set of rules and customs around; it isn’t just a drink, but a culture of drinking.
1. The Chinese only cheer with alcoholic beverages. Baijiu’s distinctive aroma is prized in China’s culinary culture and is extremely strong, so it’s often served with food and enjoyed over a meal. Cheering frequently is common, but only use your alcohol glass to do.
2. Cheer with two hands. Using two hands is a staple of courtesy in many Asian cultures from everything to cheers to exchanging money. It’s a gesture showing you’re not conducting bad-faith business behind your back; that you are engaging with two open hands and respect.
3. Where your glass touches theirs is symbolic of your relationship. The Chinese notice where the rim of your glass is in relative position to theirs. If you touch the lip of your glass below theirs, it means that you have respect for them. If they position the rim of their glass below yours, then it means they have respect for you. This can become a competitive sport when both sides equally respect each other, which can lead to a joyous friendship once the other party realizes you are well versed in the culture and maintain a low ego.
4. With tea or water, you should only pour till the glass is 70% full. This may not seem very courteous in Western culture, but in Chinese culture, this is a must. If you fill a cup of tea to the brim, you are telling your Chinese client you are finished speaking with them and are implicitly asking them to leave the table. Doing so is bad for business, bad for rapport, and bad for future dealings. Don’t give offense (or at least, not by accident.)
With a beer or hard liquor, it’s the opposite of tea. You should fill the glass 90-105% full, to demonstrate generosity and goodwill. It’s cool to overflow and spill just a little bit. Some people even attempt to show how much surface tension the beer or liquor will demonstrate before it overflows, similar to over-pouring sake into wooden boxes when served at traditional Japanese establishments. It’s a sign of generosity, and good times.
Another thing to note is that Chinese beer cups or liquor glasses are generally not very large. Some are as small as thimbles and some about the size of a double shot glass. They’re for sipping, not shooting, so take it easy.
