The majority of the people of Yazd are Persians, and they speak Persian with Yazdi accent different from Persian accent of Tehran; but there are also small populations of other Iranian ethnicities in the city such as Azerbaijanis and Qashqais who speak Persian as their second language.
To deal with the extremely hot summers, many old buildings in Yazd have magnificent wind towers, and large underground areas. Several other city traditions are the Muslim parades and gatherings, which are mainly processions called azadari held to commemorate the events experienced by the main Islamic martyrs and other important figures. These huge public gatherings created a series of spaces which, since most are near important urban monuments, are used at other times as hubs from which visitors can tour the main spots in the city.
Yazd's confectioneries have a tremendous following throughout Iran and have been a source of tourism for the city. Confectioners workshops (khalifehs, or experts) keep their recipes a guarded secret, and there are many that have remained a private family business for many generations. Baklava, ghotab and pashmak are the most popular sweets made in the city.
