After planting, they are fully watered and placed in the shade. The planting of Manjusri should be planted once every 2 to 3 years to keep the plants healthy and blooming, otherwise the growth is not prosperous and the flowering is scarce.

There are many kinds of set screws. The common ones are as follows: according to the end part, there are conical end, flat end, concave end, oblong cylinder head, etc;
According to the head part: slotted, hexagon socket, square head, etc. Tapered end screws and concave end screws with sharp ends can be used to directly top the parts, and the concave end is more reliable and can bear greater force; Taper end screws without sharp points must be drilled in the parts. The flat end is used to top the tight plane, which does not damage the parts, but bears limited load.
Slotted screws have small tightening force and are often easy to screw off. Generally, they prefer hexagon socket head; The tightening force of square head is the largest, but it can not be embedded in parts, and its use is limited. In order to prevent loosening and withdrawal of threaded parts, a set screw can be drilled at the cross seam. The long cylindrical head screw at the top end is used in the keyway of the shaft to lock and prevent circumferential rotation. It can also be used in general unimportant occasions when the key slides in the keyway of the shaft.
