The last step is to make a finger-sized stamen, fix it at the top of the flower stem, then tie the flower with nylon thread from small to large and start plastic surgery. The smallest piece inside covered the stamens, and the other flowers were pulled out. Note that when pulling out, the index finger is pulled out, the thumb and middle finger are pushed in, and the three fingers are done at the same time. That is, the two sides of the flower bend inward and the middle bends outward. If you want to be in bud, don't pull the whole flower too much. If it is blooming brilliantly, pull a little.
