Here is a green tea field in Hadong, South Gyeongsang Province.
Along mountain slopes, wild green tea trees are showing off their splendid, greenish figures.
Due to its warm climate, Hadong is home to a 1,200-year-old history of green tea plantations since the Silla Dynasty.
With a river running near Hadong, the town is foggy and humid.
Hadong is also an ideal location for the cultivation of tea trees because its temperature difference between day and night is great.
The green tea harvest begins in spring as its new buds come out.
The harvest along the slopes is done only by hand.
[Kim Tae-Jong, green tea farmer]
"It's a labor-intensive industry as tea fields are located in the mountains. Labor costs account for about 70 to 80 percent of tea production costs."
The next process is to roast the tea leaves.
During the roasting process, the tea leaves are quickly withered and heated to a very high temperature in the cast iron pot.
