As for the Tijaniyya order in China, Singapore, and the neighboring countries, the first major scholar of the Tijaniyya to visit China and Singapore was Sheikh Ibrahim Niasse al-Kolokhi (may Allah be pleased with him), as will be seen in the following image.
His grandson, Sidi Muhammad al-Mahi Cissé, was the foremost figure in spreading the Tijaniyya in those countries.
Until today, the banners of the order continue to be raised there under the leadership of those whom Sidi Muhammad al-Mahi Cissé (may Allah be pleased with him) appointed as representatives.
Here are some of the images and videos.
