What kind of wood is Jieshi's coffin?

According to Jiang's instructions before his death, his coffin was placed in the "Cihu" in Lifu 'an Village, Daxi Town, 60 kilometers away from Taipei. Chiang Kai-shek received three highest medals with his body: Jade Picking Medal, Blue Sky Medal and Guoguang Medal, as well as four books he often read: Three People's Principles, Three Hundred Tang Poems, Bible and Clear Springs in the Desert.

The docent of Cihu said that according to the information of the management office, the marble coffin has two keyhole, one in the mausoleum management office and the other in the hands of the descendants of the Chiang family. It is said that the coffin has not been opened at all for decades.

According to the data, two keys must be inserted into the marble top cover at the same time to open it. However, if you look at the sarcophagus carefully, you will find that there are no keyhole in the left, right and front except the sign of party emblem.

The commentator said that the only possible place is the side of the sarcophagus against the wall, but the top of the Dali sarcophagus is tightly attached with adhesive. No one knows whether it can really be opened. "So theoretically, no one knows what happened inside."
