What book? San Francisco earthquake 1906 boy lives in brothel

I read a book in the 70’s that was an old hard cover. I had to do a book report on it. It was hundreds of pages long. A boy goes to San Francisco and I believe lives in in a brothel for a time. The San Francisco earthquake of 1906 occurs and the town burns. I think the boy ends up digging for a box that contained something valuable. Do you have any idea what this book is. I thought Little Men, but a word search of that book’s text didn’t match key words I tried.

The guy might have been in his mid to late teens.

No idea, but if you don’t get an answer here, you might try the “What’s the name of that book???” group over on goodreads.com

I might try that at some other time. I will still give this thread a little longer.

I think I read that book in school too? Was the boy a Chinese immigrant?

No
