Yes it's scary.
Here is one find:
“Our system is out of green cards for the next 10 to 70 years,” she said. “You will have to wait a long time if you want to make a life here. The result has been a reverse brain drain. And we have reason to fear it.”
you can not seperate chinese people and chinese goverment, becuase chinese goverment is made of chinese people, their policy is based on their culture and tradition, if u think about how rapidly china rised, u can not deny chinse goverment is the smartest goverment in the world.

there are huge amount of LED makers in china who supply the various markets. if you want to buy good quality products, you should buy expensive one. if you are cost orientation, paid less, then the quality is poor.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
