I do recommend Combi, popular in HK, and China.
Its a Japanese brand, light weight baby stroller you can fold in one hand while you hold your baby in other hand.
Not only that, if you fold it, it can stand byitself.
So, you can hold your baby in one hand, fold the stoller in other hand, let it stand while you put your baby in baby bjorn baby carrier.
Maclaren is also popular, but not perfect for newborn, I guess.
HK is not for baby stroller user, so many steps, not barrier free.
Combi also has full flat stroller, some are cheap as they have a manufacture in mainland China.
===> after I posted this, I saw Mushi also recommended this one.
I had 2 of Combi, and am happy with it.
