Thank you for your reply, Romain and Ben!
I have tried to use two flows. One flow requests dst port 9999, the other flow requests dst port 8888. Since I use symmetric_l4 as hash, source port should be different in each request. However, these two flows go to the same link. I also tried to use tcp client server. I started three clients, three of them still go to the same link. When I tried to configure multiple IP addresses on the destination devices. The client side ping different IP addresses of the destination devices. In this case, it works. I can find the flows in my two links.

I need your help. Just now I checked the match_format() function. My understanding is that multipath_execute() function will fill in the regs member in flow structure(ovs-ofctl add-flow ovs-br0 "in_port=5, priority=100, actions=multipath(symmetric_l4, 1024, modulo_n, 2, 0, NXM_NX_REG0[0..1]), resubmit(,10)", The command key action is that writing the link result to regs in flow strucutre). Match_format will check the regs in the flow we want to match(ovs-ofctl add-flow ovs-br0 "table=10, in_port=5, reg0=0, actions=output:9", in this example, it will match reg0) and use reg0 as one part for matching the flow. Why my configuration does not work. From my understanding it should work. My god. Can you give me some help? In my last email, I have described the traffic and my configuration.
