  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 tells 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 be due to a decreasing emission beam during the outburst; (4) The
enhanced particle acceleration potential and pulsar death line may not be the
dominate factor.
