It's not that I haven't had a chance, just give a simple example. For example, if you score a goal (that is, you apply for a trademark), but the other side claims that you fouled first (the other side raises an objection), the referee will judge according to the statements and evidence of both sides and the relevant ball case. If you don't reply, it means that you don't make any excuses or even acquiescence for the other party's accusation against you in front of the referee. In that case, what do you think are the chances of passing? Ten years of professional service is worthy of si's trust.
