Last thing I purchased from China failed

Having worked in China for 4 years, 99% of the things I bought that's made in china failed, earlier this year, the one last thing that I thought would NOT fail for a while, failed. My question is, why certain items that are exported here from China don't fail, while their domestic versions SUCK ASS. List of items failed on me that's made and sold in both China AND USA below:

TV - Changhong brand, failed after 2 days, TV repair man had to come in and fix it.
Closet - the steel rod bent and it collapsed 4 months after purchase
Cordless Phone - worse than a cord phone, can't use it 3 feet away from the base
Humidifier - this actually didn't fail, it's Beijing's water that made it unusable after 3 months.
Kingston USB flash drive 8gb - fails after 3 months.
then I bought a different brand, PNY - fails after 3 months.
then I bought a domestic brand aigo - fails after 3 months as well, on the day.

Now the Hard drive... sigh...
