SEOUL, SOUTH KOREA — 5 p.m., Tuesday at the Gwanghwamun Square.

Thousands of South Koreans filled about 2400-feet-long, 110-feet-wide square with two, polarized shout-outs in English.

“We love Trump!”

“War no! Peace yes!”

The square, which’s few miles away from the Blue House that two leaders of the United States and South Korea discussed North Korea and economies Tuesday, is where major political rallies have occurred. Most recently in December, thousands of South Koreans — regardless of age — gathered and called for then President Park Geun-hye to resign at the same place.

Filled with rally-goers, the square was coated with both South Korean and American flags and colorful, anti-Trump signs waving at busy commuters on rush hours .

Amidst a melee, a middle-aged man was throwing profane words at a young man who was one of few dozens of millennials not welcoming U.S. President Donald Trump in Seoul.

The Gwanghwamun Square this early week was a chaos where both South Korean liberals and conservatives were crying afoul. The American National Anthem resonating from intercoms that were spicing up already agitated crowds was a plus.

There seemed to be a generational division at the rally. Parents and grandparents were welcoming Trump while scolding groups of millennials who believe Trump is accelerating a war on the Korean Peninsula.

On the eve

The Gwanghwamun Square on Monday afternoon was spottily filled with protesters.

It was a day before Trump arrived to Seoul.

Among the protesters was Yun Hui-sung, who was busy crayoning anti-Trump signs. About 30 feet away from him over the police barricade, tens of unhappy middle-aged Koreans were grimacing at Yun.

Those grimaces didn’t stop Yun, however. After done with making the signs, Yun, 29-year-old actor, started to videotape of himself shouting “No Trump! No Trump!” at his “No Trump Zone” camp-out.

“Trump once said, as U.S. President, he would destroy North Korea,” he said in Korean. “That means he wouldn’t hesitate to start a war on the Korean Peninsula … His remark to me is life-threatening.”

He and 14 other millennials at the camp-out shared one ideal: getting Trump impeached.

“As a Korean citizen, I want to send a message to all Americans, who want Trump to be impeached, that South Koreans together impeached President Park Geun-hye last December,” Yun said.

“And I hope the same thing would occur to Trump.”

Park’s impeachment was followed by months-long, nationwide rally by many angry South Koreans — who were appalled when realized Park’s close friend named Choi Soon-sil had maneuvered the Blue House ever since Park’s inauguration.

Across from the “No Trump Zone,” Jeon Yong-jun, along with about 30 other middle-aged Koreans, was helping unfolding a large American flag, about a half tennis court size.

Jeon, who said he’s in his 60s, said the young generation doesn’t understand “a thing.”

“Without the help of the U.S., South Korea can’t win a war against North Korea,” Jeon said in Korean.

After the sunset, most protesters left the Gwanghwamun Square. And around 6:30 p.m., a group of monks stepped up along side the square and started to recite the Heart Sutra —the Buddhist Scripture.

They were praying for all protesters, Donald Trump and South Korea.

Trump is here in Seoul

The Gwanghwamun Square on Tuesday was nothing like Monday’s.

Thousands of protesters were rallying for and against Trump, hundreds of police forces were forming human barricades all over the square, and journalists from the world were busy reporting a historic moment.

But there were also many passersby having troubles finding ways to a subway station amidst the crowds. Kim Bum-hyun, 24-year-old graduate student, was one of them.

“It’s too loud and ridiculous,” Kim said in Korean, while pointing at protesters waving South Korean and American flags. “Do they know what they are rallying for?”

Jang Soo-gil, one of many protesters supporting Trump, said he knows what he’s rallying for:

The young generation.

The 77-year-old man said he witnessed the U.S. bombing Hiroshima in 1945 that led the Korean Peninsula free from the Japanese imperialism, the Korean War, and the moment South Korea and the U.S. agreed to a military alliance in 1953.

Without the help of the U.S., South Korea would have remained a subordinate state, but the young generation doesn’t understand the importance of the U.S.-South Korea alliance which greatly has allowed South Korea to industrialize and prosper, Jang said.

“This (the pro-Trump rally) is for our young generation,” he said. “I am almost 80. How long can I live from now? Not many.”

The Gwanghwamun Square remained crowded even after sunset. The temperature was dropping below 50 degrees. But protesters were still on fire.

This time with the help of the Gangnam Style music.

All gone except one

4:30 p.m., Wednesday at the Gwanghwamun Square.

Trump left South Korea already. And every protester left except one woman.

Jung Ai-young, 59, was standing in a middle of the square, alone, while firmly holding a sign read in Korean, “The U.S. should free President Park, who’s proven to be innocent by law.”

No passersby seemed to pay attention to Jung’s lone rally. But she said she doesn’t care.

“I am neither conservative nor liberal. But I am a person who believes in the right thing,” Jung said in Korean.
