May I ask the origin of the following poem?

Zhuge Liang's letter to Zhuge Liang, but this sentence you chose is just like this one, for reference only!

From a distance, Qingshan is still evergreen all the year round, but from a close distance, human feelings are different. When flowers bloom, bees and butterflies gather together. People are sleepy, but friends and relatives are hard. Tea friends and wine friends, three thousand a day, a friend in need is a friend indeed, nothing. I dare not decide the country without saying a word, nor dare I write it in seven steps. I dare not say that coral trees are 100 feet high and glazed tiles cover thousands of layers. I hope the kitchen won't stop smoking. It is easy for a gentleman to get married, but it is difficult for a gentleman to make up his mind. Put up with a few words of natural elegance and take a step back. Make three points happy. How can green water wash away right and wrong when green hills are idle again? Make friends with virtue, but not with justice. Drink clean tea and give up messy wine. If so, the gentleman will benefit for life.
