1. Baoyun Hall 寶雲殿. This hall housed a library. Its texts were catalogued by Sengshao 僧紹 (d.u.) in 515, and again by Baochang 寶唱 (d.u.) in 518–519. In 548, Wudi received the newly arrived Paramârtha 眞諦 in Baoyun Hall. It also seems possible that Wudi used it as the headquarters of monastic administration; towards the end of the Tianjian 天監 reign era , he summoned Mingche 明徹 (?-523) there, to a post as chaozhuan 抄撰 (apparently some kind of scribe) in the sengxing 僧省 ( 'Bureau of the Saṃgha' ?).
2. Huaguang Hall 華光殿. Here Wudi issued his edict prohibiting consumption of alcohol and meat 斷酒肉文 to the Saṃgha, probably in Tianjian 天監 18 . The same hall was used as a venue for sermon/lectures and large dharma-assemblies. It was also in the Huaguang Hall that Liang Wudi made his failed bid, which Xu gaoseng zhuan anachronistically places in the Datong 大同 era,1 to appoint himself as controller of the Saṃgha. Here also the young Nizi 尼子 demonstrated her powers to recite sūtras apparently directly revealed to her by higher powers in 505–506.
3. Dengjue Hall 等覺殿. Here Wudi received bodhisattva precepts in 519, and the hall may have been built mainly for this purpose. On 11 January 526 Wudi invited the monk Daodu 道度 here to again confer the same precepts upon him.

In addition, the park contained a Chongyun Hall 重雲殿. This hall seems to have been constructed between 502 and 504, and was actually the upper part of a larger edifice called Guangyan Hall (光嚴殿?). In this hall, Wudi gave audience to eminent monks, and there were also held regular (perhaps monthly) dharma-assemblies, during which Wudi himself also sometimes preached, performed Buddhist rituals, and received bodhisattva precepts. It continued in use under Hou Jing 侯景 (503?-552) and was destroyed by fire in 559. 〔歷代三寶紀卷十五〕
