What kind of glue is used to paste the Spring Festival couplets on the security door?

Sticking Spring Festival couplets with paste is a traditional practice. The paste cooked with noodles is not only sticky and lasts for a long time, but also easy to clean when it is removed, leaving no traces on the walls and facades. It is also possible to stick the Spring Festival couplets with tape, but it should be noted that once the dust is stained inside the tape, it is easy to lose its stickiness and the Spring Festival couplets are easy to fall off.

The size of Spring Festival couplets is very diverse, and the selection of the size of Spring Festival couplets is mainly based on the size of the posted portal. Spring Festival couplets can be divided into 1 m, 1.5 m, 2 m and 2.5 m according to the length, mainly according to the height of the portal. Select the width according to the width of the entrance. Generally 15 cm to 20 cm Spring Festival couplets can be posted at the entrance of residential buildings, and the doorflowers of shops can be posted with a width of 20 cm to 30 cm. If the portal of the building is really big, it can be wider, but it can't exceed 40 cm.
