Beijing, April 15 (Youth.cn) - On April 14, 2026, the Chanfanggou Wild Plant Conservation Area in the Beijing Jingxi Forest Farm was inaugurated. Clematis acerifolia grows in the rivine, a national second-level protected plant. Beautiful yet fragile, it grows only on limestone cliffs and takes twenty years to form a large cluster. Once the cliff is damaged, the plant may stop blooming. Therefore, this area is under closed management. Photo/CFP
