I visit our Chinese chip design customers such as Huawei, Fiberhome quite a bit. The napping starts after their lunchtime, and it is more than 30 minutes. They start to break for lunch around 1130am. Since food is provided at a canteen, lunch is a fairly quick affair. Around 1230pm, lights are off. Some people have a foldable bed, like a camping bed, tucked under their desks, others nap on their seats. There are no dedicated rooms for napping. People simply nap in front of their desks. Others prefer to surf net, go for a walk or even continue to work. <i>You don&#x27;t have to nap</i> &quot;Nap time&quot; usually range between 1 to 1.5 hours. Often, vendors like us excuse ourselves so that we don&#x27;t disturb them. Even phones are off. I would say only large companies have this culture. I don&#x27;t think the smaller companies do that. Again my data points limited to chip design companies.
