is there a difference between 電視上vs電視裡? 兩個說法對吧？有沒有差別？
I believe we can add both after the word TV in chinese but there must be a slight difference in usage or meaning  no? like shang would be more the object and li may be referring to the program. thx in adavnce for your help
Depends how you look at it but you could equate them to the following English:

電視上 = on the tv
電視裡 = in the (tv) show

In the second one I'm inclined to treat 電視 as a noun meaning &quot;TV show,&quot; whereas in the first one it's more likely to just be &quot;TV&quot; on its own.
