You’ve probably heard of the butterfly effect that small changes in one place can lead to great damage elsewhere. The Toy Story II, Made-in-China, appearing on the internet, TV screens and front pages of newspapers worldwide since August, was a live show. China’s fame as “the world’s factory” was badly damaged this summer by a small, but powerful magnet (磁铁), and colorful paints on toys.

Mattel, the world’s largest toy company in the US, on August 14 announced the biggest recall (召回) of toys in its history. Among the recalled products were 17.4 million toys that had a design problem. They contained a small, powerful magnet that could harm children if it was swallowed. Another 2.2 million toys were recalled because of impermissible levels of lead (铅) in their paint.

Although the designing problem has nothing to do with where the toys were made, the reports in the western media of the recall started to draw a horrible picture in many American parent’s minds.

The toy recall issue followed shortly after recalls earlier in the year of Chinese-made pet food and toothpaste and left users all over the world worried about buying anything labeled (贴上标签) “Made-in-China”.

The recall of the toys teaches Chinese companies that quality is extremely important. However, many of the complaints by western countries about Chinese goods reflect complicated feelings about the growing Chinese economy, culture differences and various political systems.

However, more than 100 US multinational companies from many industries, including Boeing and Microsoft, signed a letter to the US Congress on September 28, to say no to the proposal against China. “Imposing (加强) unfair barriers to trade in the name of product safety is not a solution,” the companies wrote.

Toys are made for children to learn about the reality world and become more mature (成熟), however, the Chinese version of Toy Story helps lots of adults learn about responsibility, importance of quality, understanding, communications, and more.
