The official picture of Yulin Helper is based on the icon of windows7 system, combined with the icon of Helper's Chinese font. Windows stands for "technology", and 7 combined with Windows is the best and most extensive computer system at present, so 7 stands for "beauty", and 7 is also a lucky number of helpers, because he is the oldest in the family, and the three words combined with helpers probably mean: help solve problems with your own technology and good service.
