Could you show me how to use 以后，后来 and 之后

以后= in the future
后来= there's a preceding event but afterwards something else happens
之后= after something

eg: 以后再说吧
lets discuss this in the future
eg: 他说他喜欢看电影后来他又说他不喜欢看
he says he likes to watch movie but later on he says he doesn't like it.
eg: 做完作业之后我去了洗澡
after finishing the homework I went to shower

以后 (yǐhòu), 后来 (hòulái), and 之后 (zhīhòu) are all used in Chinese to refer to a time in the future or after a certain event, but they have slightly different connotations.

以后 (yǐhòu) is used to indicate a time in the future in general and has a more distant or indefinite connotation. For example, "以后我们再见" (yǐhòu wǒmen zàijiàn) means "See you later."
后来 (hòulái) is used to indicate a time after a specific event or period and has a more immediate or definite connotation.
之后 (zhīhòu) is similar to 后来, but with a more neutral or passive connotation. For example, "我们吃完饭，之后去散步" (wǒmen chī wán fàn, zhīhòu qù sànbù) which means "We'll take a walk after we finish eating."

"以后" (yǐ hòu), "后来" (hòu lái), and "之后" (zhī hòu) are all words used to indicate the future or a later time. Here's how they can be used in sentences:

以后 (yǐ hòu) - This is used to refer to a time in the future after the present moment. For example:
我们以后会有很多机会再见面。 (Wǒ men yǐ hòu huì yǒu hěn duō jī huì zài jiàn miàn.) - We will have many opportunities to meet again in the future.

后来 (hòu lái) - This is used to refer to a time after a previously mentioned event or situation. For example:
我们在一起的时候很开心，后来我们分开了。 (Wǒ men zài yī qǐ de shí hòu hěn kāi xīn, hòu lái wǒ men fēn kāi le.) - We were happy when we were together, but later we separated.

之后 (zhī hòu) - This is used to refer to a time after a previously mentioned event or situation. It is similar to "后来" (hòu lái), but can also be used to describe a sequence of events. For example:
我吃完饭之后去了商场。 (Wǒ chī wán fàn zhī hòu qù le shāng chǎng.) - I went to the mall after I finished eating.

In summary, these three words are all used to indicate a future or later time, but each has a slightly different connotation and usage.
