Among the 47 statutes added in 1740 under Qianlong Emperor, Statute 2 ("Charts/Tables of Mourning Attire", 《喪服諸圖》) and Statute 3 ("Code of Attire", 《服制》) dealt with mourning attire completed with charts. According to Qing law, one had to observe a period of mourning when a relative died. The closer and more senior the deceased family member, the longer the period of mourning is dictated by law. The mourning period range from three months to three years. During this period, the bereaved had to stay at home, excuse himself from public service, refrain from celebrations of all sorts, and practice abstinence, among other things.
