Like China, many other countries see spring's coming as blessing(祝福) and happiness.
In the Republic of Korea, people also greet spring by preparing a large meal. Tteokguk, a soup dish with rice cakes, is a traditional food at the New Year dining table. The round rice cakes look like coins, and people eat them, hoping to become rich in the coming year.
In India, people celebrate spring with a traditional Hindu festival called Holi, also called the "Festival of Spring". It is usually during February and March every year. Dancing and singing are how Indian people celebrate spring at the festival.
Russians celebrate Maslenitsa in spring. The festival is celebrated at the end of February or in early March each year. People will make round pancakes into yellow to show their thanks to the sun, and in the dark night, people light fires for celebrations.
In the USA, there is a special event to celebrate the spring's coming. People burn(燃烧) socks to show they can go barefoot(赤脚) when the weather warms up. It's a hope to have the winter end soon and the spring come early. People in the USA also do the spring cleaning to drive away bad things.
