Hi, to your questions:
1. take mtr from Jordan to Tsuen Wan. Then leave from Exit B1 and take bus 81 to Lo Wai Road, Yuen Yuen Institute.
2. take MTR to Sha Tin Station. Leave the train station and follow the sign showing the way to the monastery.
3. Chuk Lam Sim Monastery is closer to Tsuen Wan MTR Station. After you get to Tsuen Wan, walk 2 minutes to Shiu Wo Street. Then find the special minibus 85 to the monastery.
