Live trees are also common, and Christmas tree production in Mexico is now a large industry. Less-fortunate families that cannot afford live trees often seek small artificial trees, branches, or shrubs. In 2009, Mexico hosted the world's largest Christmas tree, according to Guinness, at 110.35 meters (approximately 362 feet) high and weighing in at a staggering 330 tons on Glorieta de la Palma at Paseo de la Reforma. Santa Claus, depicted in his traditional red winter clothing, appears as well. Before Christmas Day, it is not uncommon to see stands with Santa Claus. Parents take advantage of this opportunity to take memorable pictures of their kids. After Christmas Day, these stands have one or more "Wise Men". Many children get presents from both Santa Claus and the Wise Men, although they tend to get more from the Wise Men because "there are three of them". Public Christmas celebrations mix Mexican and foreign traditions. Mexico City sponsors a Christmas season display in the city's main square (or Zocalo), complete with a towering Christmas tree and an ice rink. Nativity scenes are placed here and along Paseo de la Reforma. During Christmas, it is common to hear both traditional and contemporary Christmas music. Traditional music includes villancicos (akin to Christmas carols) with popular songs including: "Los pastores a Belén"; "Riu, riu, chiu: El lobo rabioso"; and "Los peces en el río". Contemporary music includes Spanish covers of foreign music, such as "Jingle Bells". The most traditional and important Christmas decoration is the nativity scene. It is generally set up by December 12, left on display until February 2, and is found in homes and churches. Nativity scenes were introduced to Mexico in the early colonial period when the first Mexican monks taught the Indigenous people to carve the figures. The basic setup is similar to those in other parts of the world, with a focus on the Holy Family, surrounded by angels, shepherds, and animals. The figures are sheltered by a portal that can take the shape of a cave, stone house, or cabin. Above the scene is a star, often with LED lights. Since the colonial period, a Mexican touch has been introduced, starting with the use of Spanish moss covering the base. The scene is missing the figure of Child Jesus until Christmas Eve. Although all the other figures are generally proportional to the rest of the scene, the figure of Jesus is much larger – almost that of a life-sized baby.
