Is there any way to implment that putting a custom tag which is not yAxis value on the top of each bar? I have checked all bar-charts demo on Echarts offcial site, and no demo fulfilled my needs.

There is formatter option for label:

option = {
  xAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  yAxis: {
    type: 'value'
  },
  series: [
    {
      data: [120, 200, 150, 80, 70, 110, 130],
      label: {
        show: true,
        position: 'top',
        formatter: function(data){
            return 'Bar #'   (data.dataIndex 1)
        }
      },
      type: 'bar'
    }
  ]
};
