How to make my discord bot only reply question in specific channel?

I want to make my discord bot only reply to question on a specific channel. Here is the example:

Channel A:

User A: Dream!

Discord Bot: You are Dream’s big fans? Oh me too!

Channel B:

User A: Dream!

Discord Bot: "No Respond"

I want to make something like this. If it is possible, please help me! This is part of my code:

import discord
import time
import random

client = discord.Client()

@client.event
async def on_ready():
    print('{0.user} has already login!'.format(client))

@client.event
async def on_message(message):
    name = message.author.display_name
    if message.author == client.user:
        return

    if message.content.startswith("Hey Rikky!"):
        await message.channel.send('Always Here!')

    if "Rikky, tell me a joke" in message.content:
        await message.channel.send("I'm sorry, I'm not good at telling someone jokes")

client.run('My token')

Thanks for spending so much time reading this question! Thank you! (I’m using discord.py)

>Solution :

Just check the message’s channel id with message.channel.id before replying:

if message.content.startswith("Hey Rikky!") and message.channel.id == "YourChannelId":
    await message.channel.send('Always Here!')
