Each of us may be hit by many aspects, such as frustration in love, loss of influence in officialdom, failure in shopping malls, etc. There is joy in happiness, excitement in prosperity, depression in injustice, pessimism in frustration and hesitation in choice. This is life. Life is a bowl of soup with five flavors: sour, sweet, bitter, spicy and salty. You can taste every flavor. We have no choice but to adjust our mentality to adapt.
