If you are happy and relaxed, then it is recommended to climb Cuihua Mountain! It is the favorite mountain of Xi people, and now it is in flowering stage. It is estimated that there are many scenery on the mountain. There is also Mount Li, which is just a hill. Going there means seeing scenery and animals. If you can, you can also visit the Terracotta Warriors in Huaqing Pool, but it is far from the city center. Comparatively speaking, people around me go to Cuihua Mountain. The address is behind Xi 'an Translation Institute.
If you want to challenge the excitement, then you can go to Huashan. You know Huashan Mountain, one of the five mountains. However, after climbing Huashan Mountain, you will have backache for a few days, but it is still worth it.
About Taibai Mountain, I don't recommend you to go. Because there are no flowers on the mountain around May Day, the place where you want to see flowers is in the innermost part, so I guess you won't go either. The snow on the mountain has not melted yet, and it is very cold. I went on May Day last year and felt it. But I saw many foxes on the mountain ~ ~
