1816. Read that back to me! What do these characters have in common? 字 念 射 推 慰

Answer:

字  JI, aza - letter, village

念  NEN - thought, concern

射  SHA, i(ru) - shoot

推  SUI, o(su) - infer, deduce, recommend

慰  I, nagusa(meru), nagusa(mu) - comfort, console, amuse

They all have a reading that is the same backwards.
