My house is in period 7 and is facing SE. So, how to read the flying star chart when we are in period 8?
See house chart attached.

Thank you

We read a period 7 house with a period 7 flying star chart even though we are in the current Period 8.

Yes, we read the Period 7 chart but we must consider how that chart is influenced by the Period 8 chart.
The chart has not changed but you might say that the environment has. Does it support the Period 7 chart or weaken it? Are weak sectors now stronger or weaker? etc.
