Congea and Sempervivum, are which type of items?
Sempervivum Sempervivum (Brit. , U.S. sem-per-VEE-vum) is a genus of about 40 species of flowering plants in the Crassulaceae family, commonly known as houseleeks. Other common names include liveforever (the source of the taxonomical designation "Sempervivum", literally "always/forever alive") and hen and chicks, a name shared with plants of other genera as well. They are succulent perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offsets, and several species are valued in cultivation as groundcover for dry, sunny locations.
Chatang Chatang (茶汤; pinyin: chátāng; literally "tea soup") or seasoned flour mush is a traditional gruel common to both Beijing cuisine and Tianjin cuisine, and often sold as a snack on the street. It is made from sorghum flour and/or broomcorn millet and/or proso millet flour and glutinous millet flour. The Chinese name is figurative, not literal, as there is neither any tea nor any soup in this dish.
