talker id changes after logout and re-login

[Sanyuan-sanyuan]

Recently I code at my labtop and test at respberry pi. I pre-defined some contacts as triggers( only reply when A send me messages). I am using talker id from message.payload. But in most case there is no reply due to the talker id has been changed.
First, I login and use another account to send test message, then I logout and try again. The talker id's are different.
Is this normal that talker id keeps changing or how can i target a contact if not using talker id?

here are logs of messages:
First time:
WechatifiedMessageImpl {
_events: [Object: null prototype] {},
_eventsCount: 0,
_maxListeners: undefined,
id: '1965***',
payload: {
id: '1965***',
talkerId: '@E69C***',
text: 'test',
timestamp: 1697***,
type: 7,
listenerId: '@0c56***'
},
[Symbol(kCapture)]: false
}

Second Time:
WechatifiedMessageImpl {
_events: [Object: null prototype] {},
_eventsCount: 0,
_maxListeners: undefined,

talkerId: '@d5e7***',
