Maybe anyone is originally from Syria. Do Syrian people kiss hand of elder people?

"Many Syrians observe a separation between the functions of the hands. This custom is tied to Islamic principles that prescribe the left hand should only be used for removal of dirt and for cleaning. It should not be used for functions such as waving, eating or offering items. Therefore, one should gesture, touch people, or offer items using only the right hand or both hands together. This may not be strictly followed but it is best not to use the left hand unless the action is inevitable."

"Greetings

*Syrian greetings are usually prolonged and include questions about each others’ well-being.
*In formal settings, greetings involve a handshake with the right hand only. Arab men may shake hands very gently.
*If an Arab does not touch someone he greets, it is usually because he perceives the person is unaccustomed to being touched.
*Shaking a female’s hand is not appropriate unless she outstretches her hand first. Many Syrian men greet women by placing their hand on their chest and saying hello.
Informal greetings between people of the same gender may involve a hug, or two kisses on each cheek between males.
*To kiss one’s forehead or right hand denotes extreme respect, but it is not acceptable for a male to kiss a female in this manner if they are not related."
