The EP is about Li's observations on life in Beijing over the past decade through songs like Journey Home and Things That Will Never Change.

Lee, 59, who is the producer of the EP, says: "These songs are special not just for Li but for me, too."

About four years ago, Lee returned to Taipei because his mother's health was bad. Before that, he had spent nearly 12 years in Beijing and two years in Shanghai.

So, when Li, who was born and grew up in Guilin, shared his feelings about working and living in Beijing, Lee decided to write about their feelings.

Lee is known for his storytelling and conversational lyrics about romance, life and memories.

In Journey Home, Lee writes about people leaving their hometowns.

Speaking about his feelings, Li says: "One of my band members, a bassist, was an ambitious rocker. But he now runs a roast duck shop in our hometown.

"One day, I saw his photo on his WeChat, in which he was wearing an apron and had his son in his arms, with his wife standing nearby.

"His smile was so warm," says Li. "I then thought about going back home. But I am too proud. For me, it is harder to return home than to leave."
