Could someone help me to identify these characters on the screen walls
The character is 「尊」.

商甲前5.4.7合集6903隸定　
「尊」 (Baxter-Sagart OC: /*[ts]ˤu[n]/) was originally a combination of a wine vessel 「酉」 and two hands 「廾」, indicating the meaning (to conduct) a wine ceremony or ceremonial wine vessel. From Etiquette and Ceremonial:

《儀禮ㆍ士冠禮》

......側尊一甒醴在服北......

Etiquette and Ceremonial: Coming of age capping rites

...A jar of ceremonial wine proper at the Northern gown arrangement...


「酉」 was later replaced with the derivative 「酋」 (also wine vessel).

Eventually, 「廾」 was replaced with 「寸」 (/*[tsʰ]ˤu[n]-s/, picture of hand pulse location &gt; hand actions), gaining a sound hint in addition to its semantic function.

In case the other characters are hard to recognise, 「地」 and 「和」 are written with variants「坨」and「龢」, respectively.
