The expo will be held from April to May every year. This time, I only saw 4 greenhouses. The fourth shed is a tropical fruit shed. What is more shocking is that I saw a plant called Jinping Vine. At first, I thought it was fake. I found that it was really a gas root, yellow and purple excessive, and the straight color was bright. The third shed is better, the miniature landscape and vegetation are combined, the work is more exquisite, I have seen a lot of plants that I have never seen, and I have done a lot of characteristic areas, mainly in the countries and regions of the Belt and Road, Crescent Spring, Xinjiang, Fire Mountain, etc., pumpkins on the first class are also a variety of. Hall 8 is a good socialist made of beans and corn, generally, a bit strong theme. The last hall's peppers, eggplant, tomatoes, loofah, snakes and melons are all kinds.
