 I suggest that if there is a need, the client or the client is no longer in the first generation, their child needs to find a person who can write a letter at the time, or find another lawyer. Let such a professional come in, temporarily take on this role, and then make some adjustments. According to the situation at the time, after making the adjustment, then exit. So this is a pretty good function. It's a bit like a backdoor. It can help this letter to be done in time.
