Hello, how to get from Hong Kong Express Station to Wilmer Str, Wilmer Building? better way ? Thanks

From the HK Station, you can walk to reach Central Market, Des Voeux Road Central where you can take bus line 1 to reach Tsz Mi Alley, Des Voeux Road West and then you can walk to reach the Wilmer Building.
The building is not very far from the HK Station, so I think you can also choose to take a taxi to reach directly.
