20 13, 13 In June, a complete painted lacquer coffin was unearthed from the tomb of the Zhang family in the Ming Dynasty found in the construction site in the northern suburbs of Anbei. At present (201365438+1October 2 1), three lacquer coffins have been extracted, and at least two lacquer coffins in the western area being excavated should be well preserved and waiting for extraction. The extracted lacquer coffins are painted with phoenix, peony, crane and pond scenery, with bright colors and complete patterns. Experts say that a dry tomb that has not been excavated is an important condition for the preservation of lacquer paintings. In order to prevent these paint surfaces from curling and cracking under the influence of temperature and humidity, archaeologists wrapped the washed parts with plastic films to keep the humidity when they were unearthed.

About five or six hundred years.
