Yesterday I went to buy a little tree for my father． When I was talking with the cashier（收银员），he asked what I would be doing with this little tree． I explained that it was for my Dad， because he no longer lived at home．

The cashier just stopped and looked at me with the kindest look． He shared with me that his grandfather couldn't live in their home any longer either because he had Alzheimer's disease（阿尔茨海默症）． So I shared with him that my Dad was on the same journey． We talked about the difficulties because of the illness， not only for those who are ill， but also for their families．

When I was paying for the tree， he said， "Because this is for your Dad， let me see what I can do for you．" He took some coupons（优惠券） from a drawer and reducedmy cost by over 60%．

I thanked him for his kindness． We wished each other Merry Christmas and the best hopes for our loved family members．

On the way home I kept thinking of the kindness the offered me． It was truly a moment of "kindness given， kindness received"． I made Dad's tree more beautiful as soon as I got home． So thankful． So blessed．

In China， there are 24 solar terms（节气）in a year． And there are six of them in winter． They are beginning of winter light snow， heavy snow， winter solstice（冬至）， lesser cold（小寒） and greater cold．

Beginning of winter usually falls on November 7h or 8th． After beginning of winter， most parts of the country can start to expect cold weather． On this day， after a year of hard work， people are happy to have a rest and spend tine with family． The northern China celebrates beginning of winter as the "Small Spring Festival'"． People usually have dumplings and mutton soup on that day．

Light snow usually falls on November 22nd or 23rd and heavy snow usually falls on December 7th or 8th． When winter solstice comes， it brings the shortest days of the year and the longest nights． Many places around the country can expect the coldest weather yet． People often start counting"'nine cold periods" starting from winter solstice． Every cold period has nine days．People believe that after 81 cold days，spring will come．

Greater cold comes after lesser cold． The field is covered with snow． And all Chinese are ready to welcome the Spring Festival after it． Of course， a new round of solar terms will start．
