Superior leaders came to check how the campus TV station wrote welcome slogans

Warmly welcome (all) leaders (and guests) to visit (***) for inspection and guidance

Note: The content in brackets is written according to the actual situation, such as leaders, leaders of the Ministry of Education, Leaders of Jiangsu Province, etc. If there are guests, write "and guests". If you want to highlight a certain unit or region, add it after "visit".

In general, you should also consider how many words can be written in the slogan, even if it exceeds the length of the banner
