How to face the Qibla in Gangu Chengguanzhen
Stand where you will pray and find north first. Then turn towards west and move a further 5.4° towards north: the result is the bearing of 275.4°. The direction is close to due west, which makes it easy to remember.
Facing the Qibla is a condition of the prayer. Whoever prays inside the Sacred Mosque faces the Kaaba itself; whoever is far away, as in Gangu Chengguanzhen, faces its direction and makes a sincere effort to be accurate. A nearby mosque is a handy reference, because its prayer rows were aligned when it was built. Once you know the direction at home, a discreet mark on the wall saves you from checking again.
Why a flat map shows a different direction
This is a place where maps mislead badly: a straight line on a flat map from Gangu Chengguanzhen to Mecca points to 257.0° (west), a full 18.4° away from the true Qibla of 275.4° (west). The map line keeps one compass heading and is 89 km longer than the great-circle route. Because the Earth is a sphere, the shortest way to Mecca from Gangu Chengguanzhen first heads west, and that is the direction to face.
How is the figure of 275.4° obtained? From the coordinates of Gangu Chengguanzhen (34.7356° N, 105.3263° E) and of the Kaaba (21.4225° N, 39.8262° E), spherical trigonometry gives the starting bearing of the great circle joining them. Mosque architects and astronomical Qibla tables rely on exactly the same calculation.
Distance from Gangu Chengguanzhen to Mecca and Medina

Clocks in Gangu Chengguanzhen run 5 hours ahead of Mecca all year. Prayer times, however, depend on the sun at your own location, so always use the prayer times of Gangu Chengguanzhen rather than those of Mecca.
