This small collection of articles contains the author's feelings about life, insights from work, and thoughts gained from reading. Dear readers, you can savor it carefully before tea and after dinner. Reading the essays in the small collection is like tasting a cup of tea. It may go into your mouth with endless aftertaste, or it may not go into your mouth and it will be bitter and tasteless. Where the sunflowers are blooming, I wish I could get a ray of sunshine and a moment of joy.
