macnai quoted Vivek with this note:  “Shenzhen is home to many global players in the photonics industry and is one of the leading locations to find talented engineers in our industry,”

Ok, so who are some of the "global players in the photonics industry" with offices in Shenzen?  In other words, what is the justification for that claim of Vivek about Shenzen being "home" to many global payers in the photonics industry?

A few links below will give at least a sampling of those "many global players in the photonics industry":

Also to be considered should be the pursuit of photonics at the university level in Shenzen:

College of Optoelectronic Engineering - Shenzhen University(SZU) - Apply online – SICAS | Study in China

Center of Information Photonics and Energy Materials - Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences (siat-sz.edu.cn)

Of course, if none of the above convinces you that Shenzhen is "home" to many global players in the photonics industry then maybe you will be more impressed by what is opening in Shenzhen in 2024:

World's Largest Legoland Being Built in China's Shenzhen - Variety

Now, that should be thrilling for even the longest longs who are POET investors... world's largest.. but you have to wait until 2024.  Somethings are just worth waiting for, like Shenzhen Legoland and POET's Sales and Revenue, eh?

Or spend some time at Happy Valley Theme Park in Shenzhen where "You will be intoxicated with the most fashionable hip-hop performances accompanied by the strong rhythm and shocking music."  Yes... "shocking music"!!!  Maybe it will make you forget all about Photonics???
