Typhoon is a kind of cyclone and should be rainy. But why is the typhoon sunny without wind and rain?

It is said that the cyclone system produces precipitation because the cyclone center is updraft and the typhoon is the most powerful cyclone system. Strong updraft accumulates at high altitude and there is nowhere to go, which will force the typhoon to form a downward airflow in the center, that is, the typhoon eye. The downward airflow will produce sunny weather, so the typhoon eye is clear and cloudless.
