Usually two routers can ping each other by ping x.x.x.x in Cisco devices
But in Juniper, we have to do like this ping 6.1.1.1 bypass-routing interface ge-1/1/3

Do you think we can ping like this ping x.x.x.x in Juniper? If so, why I cannot ? Thank you

You can ping with ping x.x.x.x in Juniper (that will create continuous ping), but you need to have routes properly configured. bypass-routing means that ping is ignoring routing table. Problem can be source interface (e.g loopback - not directly connected interfaces) you are using for ping and one or both routers missing route to each other's loopback.
bypass-routing      —      (Optional) Bypass the normal routing tables and send ping requests directly to a system on an attached network. If the system is not on a directly attached network, an error is returned. Use this option to ping a local system through an interface that has no route through it.
ping - other options
ping host   <---  host       —      IP address or hostname of the remote system to ping.
