Today, the linux Write and non-deletion requirements are finally met.
POSIX ACL

The requirements of our company are as follows (I only need to make the steps required by our company and correct them slightly)
The shared directory To_manager only has full permissions for the manager User.
Other users only have the permission to copy and create files to this directory. However, files cannot be deleted, and files cannot be copied or read.

Steps:
1. Change smb. conf as follows

[To_manager]
Comment = To_manager
Path =/To_manager
Writable = yes
Create mask = 1600
Directory mask = 1600

2. Let Linux support posix acl (this posix acl function is officially supported on Linux kernel 2.6, and then back-port to 2.4 kernel. ACL can be used in common file systems, such as ext3, xfs, jfs, and ReiserFS. Of course, you must start the ACL when compiling the kernel .)

You can also add the following options to/etc/fstab:
/Dev/sda1/home ext3 acl 1 2

3. Write a small script

#! /Bin/bash
Mkdir/To_manager
Chmod 777/To_manager
Chown manager: manager/To_manager
Chmod o + t/To_manager
Setfacl-m d: u: manager: rwx/To_manager

Run the script and restart smb.
