Hungarians are highly superstitious about clinking glasses, whereas in China, it's advised not to raise your glass higher than the elderly or the host.
When traveling to these countries, it's essential to observe the local custom of toasting with the natives.
Armenia
Each table is accompanied by a tamada (toastmaster), responsible for delivering congratulations and ensuring everyone is in high spirits. If you're drinking beer, pour a glass for someone else using your own bottle. The last person to drink in this round will foot the bill for the next round for everyone.
When toasting, say: Կէնաձդ (gen-ots-it)
Germany
When toasting, it's essential to make eye contact with others. Otherwise, you might face the consequence of 7 years of not-so-good 'rainy weather.' When drinking in Germany, remember to clink glasses to make a 'leng keng' sound with those accompanying you.
When toasting, say: Prost (prohst) for beer and Zum wohl (sum vohl) for other drinks.
France
Eye contact while drinking is also common practice in France. When pouring your drink, be mindful not to overflow the glass and remember to take small, gentle sips instead of causing a loud slurp.
When toasting, say: A votre santé (ah vot-ruh sahn-tay)

Czech Republic
Czechs never cross their arms when raising a toast. Not adhering to this rule might jeopardize your romantic life.
When toasting, say: Na zdraví (naz-drah vi)
Ireland
When shopping for yourself, it's customary to also purchase drinks for others. However, there's no need to worry because that person will contribute towards the bill at the end of the drinking session.
When toasting, say: Sláinte (slawn-cha)
Hungary
To avoid being attacked in Hungary, refrain from clinking glasses to make a 'leng keng' sound. This law is related to a legal event in 1849 – the execution of the 13 Martyrs of Arad. Legend has it that Austrian soldiers celebrated by clinking beer glasses because the revolutions in Hungary had been crushed.
When toasting, say: Egészségedre (egg-esh ay-ged-reh)
Russia
In Russia, it's customary for everyone to give a long toast before finishing their drink. Once you pick up your glass, it's hard to set it down until it's empty.
When toasting, say: Будем здоровы (boo-dem zdo-ro-vee-eh)
China
Unlike in France, Chinese people prefer to pour their glasses full. When you say 'cheers' and raise your glass, be careful not to hold your glass higher than that of the elderly or the host. This action is considered disrespectful.
When toasting, say: 干杯 (gan-bay)
Japan
In Japan, you're never allowed to pour your own drink. It makes you feel like the boss. However, you still need to pour drinks for those drinking with you.
When toasting, say: 乾杯 (kan-pie)
South Korea
In South Korea, it's also not customary to pour drinks for oneself. The tradition of giving and receiving drinks to others is highly important here. The server pours drinks from a bottle, and the recipient holds the glass with both hands.
When toasting, say: 건배 (gun-bay)
