There are mountains, water, birds, flowers and fish in these two sentences, which outline a beautiful fishing environment and pave the way for the appearance of characters. The last two sentences of the word write fishing on the waves of smoke. The "oblique wind and drizzle" in the last sentence is not only a true description of the scenery, but also meaningful.
