How to replace CONCAT in sqlite?

Question

SQLite

Hello. I have a MySQL query:

SELECT * FROM people WHERE CONCAT (pbfirstName, pblastName, pbcity) LIKE "%со%" OR CONCAT (pbfirstName, pblastName, pbcity) LIKE "%fi%"

Please tell me how can I rewrite it for sqlite. As far as I understand CONCAT in sqlite, it is ||. But I didn't get a valid one.
