     I wear what I feel is comfortable and convenient. Decades ago, my 10-year-old Italian nephew asked me for jeans from Canada when I visited.

     Upon seeing them, he claimed they were not Levis. "What does Levis mean?" I asked naively.

     Later, I was preparing to come to China when my Sichuan friend ordered jeans for her daughter.

"You mean Levis, I guess?" "No, Benetton," she said.

     Living in China I realize the effect brands have on people here. Once I bought a pair of sandals

because I needed sandals. Many people told me, "Wow! You wear them? You have money!" I didn't

know why they thought 150-yuan ($22) sandals were for wealthy people. I had never heard that brand

name (which I can't remember) before.

     While visiting my family in Canada, we were talking about fake products(假冒商品) in China. As a

writer, I don't accept that readers pirate(盗版) my books and I would consider myself a thief if I ever

buy them. A young relative asked, "What about your purse?"

     "What's the problem with my purse?" I countered.

     "It's a Yves Saint-Laurent; do you mean you paid the full price?"

     "How can you think I bought a YSL? I bought it because of size, color and price."

     She picked up the purse and pointed to the steel YSL on it. Believe it or not, I had not noticed it till

then.

     When Pearl Market used to sell watches, I happened to need one and went there for the large choice

they offered. What I wanted was a watch to see the time, I insisted.

     They had no Chinese brands, only Cartier, Citizen, Seiko, Rolex. Having refused several ming pai

copies, I was leaving without buying when I saw a black one.

     "Diesel, what a strange name for a watch," I thought. Wasn't diesel something that went into a gas

tank? The business deal went quickly; I offered 35 yuan and left with the watch.
