The tendency to blindly follow fads could be another reason for business failures, he says.

"For some people, running a vintage clothing business makes them cool and trendy."

Trends constantly change, he says, and many people try this thing and that, and barely stop to think about what is really good for them.

"They spend money and a lot of time trying to keep up with trends, afraid of being left out of the loop."

Liu says most people would not be obsessed with a certain way of dressing as the result of watching a movie. But he reckons one of the aims of movies is to disengage people from reality for an hour or two, and he likes to think that after having watched a film he will have learned something from it.

However, his business leaves him little spare time. One of the shop assistants who works for him, Lin Yuyang, says Liu once worked 30 days without a break then decided he really did need a day or two off, but within 24 hours appeared in one of his shops.

Liu says: "I love to talk with vintage-clothes lovers in my shop, and I love the fact that this leaves an impression on them, and we that we can see eye to eye. It's really so cool."

He also enjoys spending time with the products he has discovered and presenting them to customers.

But ultimately Liu, who calls himself Lucky Luke, counts himself fortunate that though this second chapter of his life is a little different to the first, in one way it is exactly the same: he is able to do something he loves.
