How to move cursor one line down with API in the way like the default 'j'?

Question

For example, I have this in the buffer:

line1 .... A ....
line2 B
line3 .... C ....

Follow these steps:

1. At first it's in Normal mode and the cursor is under A
2. Press j and the cursor will move to B
3. Press j again and the cursor will move to C

Seems like internally Vim maintains a "user-expected" column position so when it goes from line2 to line3 it smartly restores the correct column position.

So how can I get the same behavior with Lua API ^{(like vim.api.nvim_win_set_cursor())} when moving the cursor one line down?

As reminded by @D.Ben's comment, the following workaround works for me:

vim.cmd('norm! j')
