Some are. There are other similar varieties used as well: one that is a de árbol variety, another that is a cayenne, another that is a mirasol (though one does not see those here much).
Hot peppers are not found in 'Chinese' dishes (if I may put a finer point on the question); they are found in just two of the eight major cuisines of China, Hunan and Szechuan, and probably only one or two of the numerous sub-cuisines (southern Fujian is the only one I can think of though and, still, they are not frequently used there).
In restaurants here I have seen all those I've noted--but have also rather often seen one or another of the Thai chilies. Those are characteristically longer and proportionately narrower than the others mentioned.
