Are the words on the incense burner divided into front and back?

The word is reversed and incomplete. Seal script: Ming Xuande year system. There are four kinds of * * * found in Xuande Furnace, namely, one character, two characters, four characters and six characters, such as "Xuande", "Xuande Year System" or "Daming Xuande Year System". These figures are square and round. Most of them are square boxes, and the words in the boxes are regular script. The font strokes are regular, vivid and natural, neat and delicate, and the structure is rigorous. Emperor Xuande did not consider the export when he built the furnace, so it was not necessary for his organ workshop to print the country name and year number on the furnace at the same time. Therefore, it is considered that the four-character year number is the identification of the true Xuande furnace, the one-character model is the product of the people's workshop, and the six-character model is the imitation of the Qing Dynasty.
