I'm create project based on ancs example project and add one custom uuid(use 16 bit UUID) that has two charactristic(16bit UUID) and also added a hid service, and I found I should change the VENDOR_SPECIFIC_UUID_COUNT value. But I do not know how to calculate this value? Does nordic has some guide on how to calculate the vs_uuid_count? Does this value include the 16 bits UUID?

Actually, you don't "calculate" the vs_uuid_count. It is just the number of services used by the softdevice. It is used in ble_stack_init. I don't know the ancs services and characteristics by heart, but I guess it is 10 of them.
If you look in services_init(), you will see that it initializes 10 services, so that is the reason vs_uuid_count is set to 10. If you set it to 9, you will see that services_init() will fail, because the 10th service you try to init will return err_code = NRF_ERROR_NO_MEM.
In ancs project, I think it should be set to 4 rather than 10, since it totally add four 128 bit Base UUID.You said it is set for ble stack and I should not change this? So If I add my custom 128 bits uuid, still no need to change this value?
