 They are generally given by the elders and adults, where a greeting or offering health and longevity is exchanged by the younger generation.Common greetings include ""Sống lâu trăm tuổi"", ""An khang thịnh vượng"" (), ""Vạn sự như ý"" () and ""Sức khỏe dồi dào"", which all relate back to the idea of wishing health and prosperity as age besets everyone in Vietnam on the Lunar New Year.The typical name for lucky money is "lì xì" or, less commonly, "mừng tuổi".
