Write about Vietnamese customs.
Hello guys. Today I will tell you about the greeting custom in Vietnam. Vietnamese people usually
greet by shaking hands and bowing. Sometimes they hug if they're close. Unlike other countries in
the West, Vietnamese people often avoid greeting by kissing the cheek. Besides, some businessmen
greet by exchanging business cards and shaking their hands firmly. They often exchange
business cards when meeting business partners or customers. They often give and receive it
with both hands as a show of respect. Vietnamese people usually talk about their business, their
health, hobbies, sports, games.... in small talk. Finally, We should learn more about the greeting of
many countries in the word to facilitate communication. Like other countries you shouldn't talk
about the salary, age and religions while talking because it is private.
