In order to better carry forward the tradition of "raising chrysanthemums" in the park, young Liu Ning has the courage to explore and innovate. She combined traditional protection technology with modern new technology to create a new world. She used the method of cross breeding to cultivate new varieties, and cultivated a single chrysanthemum variety with large flower pattern, early flowering and strong stress resistance, which enriched the chrysanthemum varieties in the park.

After three years of continuous screening, in 20 13 years, from more than 600 pots of newly bred chrysanthemum varieties in 100, she selected six chrysanthemum varieties with stable characters, huge flower shapes and bright colors, which were named Qionghua Jin Hui, Qionghua Evening Scene, Yu Tai Chunfeng, Yu Tai Gaixue, Yu Tai Dewdrop and Qionghua respectively. After the appraisal by the expert group of China Chrysanthemum Research Association, the new chrysanthemum varieties she cultivated were affirmed by experts and won new honors for Beihai Park. Therefore, it was awarded the title of "China Chrysanthemum Art Nova" by China Landscape Architecture Society.

In the face of honor, she did not dare to slack off, but continued to learn from her predecessors. In this way, Mr. Ye Jialiang, a national master of chrysanthemum art, recognized Liu Ning as his disciple. In every critical period of chrysanthemum cultivation, Liu Ning will go to Tianjin by train to meet Master Ye, who will teach her the key parts and techniques of pruning chrysanthemums. Chrysanthemum cultivation techniques in Liu Ning are increasing day by day. Now is a good time for chrysanthemums to smell crab roe. Going to Beihai to see the most beautiful chrysanthemums is a great enjoyment of life.
