Help me improve English ablility's idol

I have a health hobbit which is eating breakfast every morning. There is a breakfast store around the corner near my home. I used to order a tuna egg cake and a cup of milk tea. This store has the most delicious the tuno egg sake I ever eaten.
One day, before I place an order, I heard owner was speaking fluent English with other customer who is Caucasian. I was shocked. I thought he just a normal cooker. how can he speak such perfect English without accent? And then I ask him," Have you ever studied English oversea”, he say, " No, I never been to any western counties. " He told me that when he was a junior high school student, he was interesting in English. He read a lot of foreigne novels and watched American TV episodes without caption. He gave me some suggestions about how to improve my English. The most important thing you have to keep in your mind is studying English has no short cut.
He is different to other breakfast cooker because he has English ability. he can have a conversation with English speaker customers that makes his life more colorful.
