Mr. Xu is still alive, but his mind has rotted. The body may live in tomorrow, but the spirit stays in yesterday. Poor thing.

Some people's remarks are out of tune with the times because they walk too fast and have advanced ideas, which are beyond the understanding of their contemporaries. People in the future will compensate him and admit him. Some people's remarks are out of tune with their surroundings because they walk too slowly and are left behind by the times, and their ideals and visions will never be realized.

Mr Xu obviously belongs to the latter. The good old days he longed for, the time when all his wishes and dreams were met, will never return.
