The magnetar SGR 1935+2154 is reported to have an anti-glitch, accompanied by fast radio bursts, and transient pulsed radio emission. In the wind braking model, this triplet event tell people that (1) SGR 1935+2154 does not have a strong particle wind and can be approximated by magnetic dipole braking in the persistent state; (2) Its anti-glitch is due to an enhanced particle wind, similar to the first anti-glitch in magnetars; (3) Its transient pulsed radio emission may due to enlarged and decreasing emission beam during the outburst. The enhanced particle acceleration potential and pulsar death line may not be the dominate factor.
